Born to Run? - Part 1

Hello folks!

Racing has been keeping me busy for the last few months. 

Notable sessions have included….

The last event in the Dark and White Trail Quest series, where I achieved my highest placing to date, finishing 7th in the senior male category in some very cold and challenging conditions. 

I returned to the Peak for a 5 hour running epic, with my good mate Dan Shrimpton - himself an awesome Ultra runner. The main purpose was to reccy the route for an up-coming fell race (the Edale Skyline). We endured 25 of the toughest running miles the Dark Peak had to offer, including wind, rain, hail, snow, dense fog and knee deep peat bogs. It became one of those character building sessions that train mental as well as physical toughness! We loved every minute of it!

It obviously served Dan well as I heard today that he has just won the “Hardmoors”. Part of the Vasque Ultra series, the Hardmoors is a 55 mile race over some of Yorkshires toughest fells. Amazing effort Dan!

Bakewell next for the "Open 5" adventure race. A 5 hour MTB / Fell Running navigation event. I felt super strong on the 3 hour bike section and managed to clear all the controls points (first time I've achieved 100%). Some navigational errors cost me dearly on the run but I still managed to clear all but one control. This was my best performance in an adventure race to date. As a self confessed "amateur" with map and compass, I was dead chuffed to be mixing it with some of the region's best adventure racers, including athletes from team Accelerate and Berghaus. 

I ran the Ashby 20 with my good buddy Hasseb who I am "guiding" for the London Marathon. We used the race to trial our pacing and feeding strategy for the marathon. Things went pretty well and we held our target 3hr marathon pace for the duration. Haseeb had to dig deep and navigate a treacherous last mile, but he really showed his mettle. 2hr 17mins was a pb for Hasseb so job done.

I was also very proud to gain a County vest following a reasonable performance in the Leicestershire County Cross-Country Championships. My call-up to represent Team Leicestershire in the Inter-County Cross Country Champs came slightly out of the blue. The event was also a World Cross qualifier event so lets just say the quality of the field was a little higher than I am used to!  

Myself looking a little pensive before the start of the Inter-Counties

Needless to say, the event was a real eye opener. 

Watching "real runners" float effortlessly over the ground got me to thinking. Why do triathletes make it look so hard! 

Ok, fair enough - the top guys look pretty impressive, but the vast majority of age-groupers (myself included) tend to lack that effortless grace that we see in elite runners.    

I have been aware of this in my own running for some time now and it’s been something I've been actively trying to correct - and, I'm glad to say, with some success.  

And this brings me neatly onto the subject of my latest blog post...

Running form - can we make changes to the way we run to increase speed and efficiency without requiring extra effort or energy?
 

Read on to find out.....
 

So why do we run the way we do? It's an interesting question. 

Few of us are actually taught how to run - it's the most natural thing in the world. Nobody really feels they need to be told how to do it correctly.  

But the reality is few of us do run as well as we could and some very simple changes to our running form could see us all running more efficiently and, ultimately, faster. 

As kids we spend a great deal of our time running around - just for fun. In fact, if you want to see an example of great running form - look no further than kids running around a park in bare feet! 
 

Now there's a term you've all probably heard a great deal in relation to running - "bare feet". Right now, it seems to be the new running revolution. People around the world are ditching the super squishy trainers in favour of a bizarre array of "bare foot" running shoes.

I’m actually going to devote more time to the mechanics of the running gait and foot strike in Part 2, so watch this space!

But what about muscles? - Ever stop to think about the muscles responsible for running? 

Ask anybody which are the muscles responsible for powering you down the road most would focus on the leg that's in contact with the ground. Quads? Hamstrings? Glutes maybe? These are all big muscle groups and you could be forgiven for thinking that these are the muscles largely responsible for forward motion.

The reality is somewhat different.

For sure, the previously mentioned muscles are certainly essential for the action of running but they are largely useless unless we are able to provide a stable working platform (a strong core) and a "force" to counteract the driving action from the prime movers.

Think about pushing a car. You lean against the rear window and push with your muscles including your quads, calves, glutes and lumbar muscles. The mass of the car offers a resistive force that allows these muscles to fire. Slowly but surely the car inches forward…

Now imagine the car disappears….pooof! It’s gone!

What happens to all those muscles that were flexed and generating huge amounts of power? These muscles no longer have a force to work against – they relax and you fall over.

It would be the same when we run, if we were not able to provide a counteracting force.

However, when we run, we don’t have a car to push against (although it can feel like it sometimes!), so where does this opposing force come from?

Well this is where our “swing phase leg” and gravity comes in..

The swing phase leg, or the non weight bearing leg, as it moves dynamically through the air generates a pull on your body’s centre of gravity. This advancing centre of gravity, and the fact that the weight bearing leg is anchored to the ground, allows a rearward thrust to be generated, et voila, forward velocity!

Also don't neglect your arms. Don't just let them dangle around by your side. Try it in fact. Have a go at running fast with your arms in your pockets. Note how your body twists and your shoulders roll? This is your body trying desparately to balance out the forces from your legs.

So now try again, but this time with elbows flexed at right angles (or there abouts) swinging forward from the shoulder in line with your direction of travel (not side to side, across your chest or round in circles!). Imagine punching a cushion with each alternating fist. The arm swing should be forcefull and yet controlled and actively "stopped" ahead of the body. This stopping action should be timed to coincide with the end of the opposing leg's swing phase. These two actions then combine to provide an effective opposing force to the powerful weight bearing leg. 

So, back to the legs. The important question is… Which muscles control your swing phase? Well, as a group they are referred to as your hip flexors.

The “Hip Flexor” is not a single muscle as some might believe, but a generic term referring to a group of muscles who’s job it is to flex the femur (pull the knee up).

The Psoas Major, Psoas Minor, Iliacus, Rectus Femoris (one of your quads), Sartorius, Tensor Fasciae Latae (or “ TFL”, which is a glute muscle), Pectineus, Adductor Longus, Adductor Brevis and Gracilis are all hip flexors. So next time somebody complains about their hip flexors – you can ask “which one of the 10!”. Then go on to really impress them, by naming them all!

However, of these, the Psoas (Major and Minor) the Iliacus and the muscles of the inner thigh are the most important of your hip flexors for generating an explosive, powerful swing phase leg motion.  Unless specifically trained, they can fatigue quickly, your quads and claves, while still full of beans, have nothing to work against and your dynamic, effortless stride becomes an inefficient shuffle.

We’ve all no doubt experienced this toward the end of races – particularly triathlons where hip flexors are also put through the mill on the bike. The resultant shuffle is a direct result of your hip flexors packing up and leaving the party!

Unfortunately, the hip flexors are one of the harder muscles to train and one of the first to loose condition when you de-train.

They can be strengthened most simply by practicing running fast. Simple really - to run fast, you gotta train fast! Hours of long, slow distance training will improve your aerobic condition but it will not provide the sufficient stress or force required to recruit these "fast running" muscles. You may feel fit as the proverbial butcher’s dog off a winter of Long Steady Distance, but come race day, your hip flexors won’t know what’s hit them!

So lesson one, if you want to run fast in the spring, don’t neglect fast training sessions during the winter!

Tempo runs, intervals and fartlek training can (and should) all be included in the off season.

Other terrific ways to train your hip flexors include running in snow, mud or thick scrub (so you have to lift your feet higher off the ground), hill repeats, climbing stairs and "Roman Chair" exercises in the gym.

There is a great way to conveniently combine many of these training methods and its called  "Cross-country racing"!  The gains in strength and speed can be huge and it should come as no surprise that most dedicated track and road runners, looking for strength and speed in the spring, run cross-country in the winter! They know the importance of strong, fatigue resistant, hip flexors!

So lets all get our hip flexors in shape, start using our arms and we’ll be ready for Part 2 where I will be looking at cadence, stride length and foot plant.

This weekend I’ll be returning to take on the Peaks again in the Edale Skyline fell race.  I just hope my hip flexors are ready to party!

Fats and the Cholesterol myth!

Ok, first a great big "thanks" to all those who have read my last blog post and left kind comments - I hope you all found it interesting and eye opening!

It's great to hear that I am reaching people - that was always my hope and my intention.

I can think of a number of people that, as a direct result of my last post (and some of the videos) are now in the process of changing the way they eat and shouting about it to their friends. Fantastic! Keep spreading the word.

If you haven't read it yet - no worries, you are here now, so maybe just read my last post before dipping into this one. Also, if you haven't watched "The Big Fat Fiasco" vids (linked in the post) then please do - they are essential viewing!

So, I spoke about food groups, in general, during my last post - but I think it might be worth delving a little deeper and talking about one specific food group in our diets and one that continues to get grossly misrepresented.

Namely fats...

More specifically, saturated fats and more specifically still, cholesterol...

So here goes...

In my last post, I spoke about the different types of food we consume to fuel our bodies during work, rest, day to day activities and sports type activity.

I also called into question the validity and health benefits of the "Low fat / High Carb" diet that we have been brainwashed into believing for several decades!

We have a number of people to thank for this myth but a certain biochemist called Ancel Keys probably sits at the top of the tree.

It was his studies in the 1950's along with a great big dollop of bad science that lead to the so called "Lipid Hypothesis" which in essence was... if you eat fats, you get fat and the associated levels of fat and cholesterol in the blood will increase your risk of Atherosclerosis (ASVD) and coronary heart disease (CHD). So don't eat fats (particularly saturated fats), eat grains and vegetable oils instead.

Tom Naughton provides a great analogy in his film "Fat Head" - a brilliant and funny movie well worth a watch.

He asks that we imagine the whole of human history (over 1 million years!) compressed into 1 year. He states that, proportionally, we have only been farming and eating grains since yesterday (when we started becoming shorter and fatter) and we started consuming processed vegetable oils about 10 minutes ago (when heart disease became our number one killer).  So after examining all this human history the "experts" (Ancel Keys among them) suggested that we all start eating what?

Yup - more grains and processed vegetable oils!!

That's right, in order to protect our heath, it was suggested that we should all eat more of the foods that we hadn't eaten for 99% of all human existence!!

Brilliant!!

Sorry.. did I miss something??

Thankfully the whistle has been blown on this hypocrisy, it's bad science exposed and the general population gradually coming round to the idea that they may have been sold a pup.

But elements of this myth still remain and a biggy is Cholesterol.

We've all heard of Cholesterol and how bad for us it is. We all know how increased Cholesterol levels can increase Atherosclerosis (ASVD), Coronary Heart Disease (CHD) and heart attack risk and we know that these increased levels are, by and large, due to consuming cholesterol rich foods like saturated fats and dairy right? Right?

Sorry.....wrong!

Again we have our friend Ancel to thank for this one following his now famous study (that got him the cover of Time magazine) were he showed a "link" between high blood cholesterol levels in different countries and increased incidence of CHD.

What he actually showed was an "association" or "correlation" and, as any good scientist knows, correlation does not imply causation. In fact, as we will see later, Ancel didn't even see an association, but he "manipulated" the data to show one. 

A great example that illustrates the inherent weakness of "observational" studies is shown in the Fat Fiasco video. It sites one such study which showed that women who were taking oestrogen (HRT) were "seen" to have a lower than average incidence of CHD, leading doctors to propose that HRT was protective against CHD. However, further "clinical" trials actually showed that HRT caused a small but statistically significant increase in risk of CHD. How could this be?

Re-analysis of the data from the observational studies showed that women undertaking HRT were more likely to be from higher socio-economic groups, with better than average diet and exercise regimes and generally more likely to look after themselves. The use of HRT and decreased incidence of coronary heart disease were coincident effects of a common cause (i.e. the benefits associated with a higher socio-economic status), rather than cause and effect as had been supposed.

So back to Ancel and his bad science. Another crafty trick he pulled was to disregard any findings that didn't suit his own hypothesis, so Aboriginal Australians were dropped from the study because they had very low levels of cholesterol but some of the highest incidence of CHD in the world. Conversely the Swiss, very high cholesterol, very low incidence of CHD. So the Swiss result was not included! These are just two examples of many nations that did not follow the link Ancel was trying to prove.

Looking at all the data - it's impossible to make any connection between blood cholesterol and CHD....

Supported by equally flawed observational analysis like the Framingham Study, the myth refuses to die....

Lets try and put this one to bed...

Firstly, some stuff you maybe didn't know about cholesterol...

Cholesterol is a very important chemical in the human body.

Cholesterol is actually a "Steroid Metabolite" and is an essential structural component of every cell of our bodies - without it our cells would literally fall apart and we'd be a pretty unpleasant blob on the floor.

Cholesterol is a potent antioxidant and a "metabolic nutrient" able to heal the body from infection and repair damaged tissue.

It helps synthesise vitamin A, D and K and without it our bodies can't produce bile or bile acids needed to digest protein.

So cholesterol is a good guy ok!

Ahhh but what about "bad" cholesterol I hear you say!

Well lets get this straight....there is no such thing as "bad" cholesterol or "good" cholesterol for that matter. Just cholesterol.

So maybe some of you have heard of HDL and LDL cholesterol. I'm not surprised, we hear these terms banded about all the time on the TV by the likes of Gloria Hunniford intent on selling some magical margarine designed to stop us all from dropping dead from heart failure.

What Gloria doesn't know is that HDL cholesterol and LDL cholesterol aren't even cholesterol! They are proteins (High density lipoproteins and Low density lipoproteins).

Cholesterol is a waxy chemical that is not soluble in the watery environment of blood so it needs to be transported within certain protein molecules around the body. That's where HDL and LDL come in.

So why is HDL (wrongly) touted as "Good" and LDL considered "Bad"

Beats me??

LDL is simply transporting cholesterol FROM the liver TO the body tissues. If you believe (incorrectly) that cholesterol is bad, then I suppose anything that transports it TO the body tissues must also be considered "bad".

This is completely and utterly wrong! Wrong wrong-idy wrong...

LDL is simply transporting cholesterol to where it needs to be in the body. LDL is just trying to help by carrying cholesterol it to where it can mop up cellular damage, repair cells and make new ones. So stop picking on it ok!

HDL on the other hand gets all the brownie points for transporting this "poison" away from the tissues. (If I were HDL, I'd spend all my time blowing raspberries at LDL - but that's just me) So where does HDL take this cholesterol? You'd assume, because cholesterol is so "bad" and HDL is so "good", it would transport it out of the body ASAP wouldn't you.

But it doesn't

It actually takes it to the liver - where it is recycled and re-used. Our bodies know how important cholesterol is. It a complex chemical compound that the body wants to hang on to. It's far easier to recycle than it is to re-manufacture.

A great quote from Natasha Campbell McBride, MD goes something like this...

Calling HDL "good cholesterol" and LDL "bad cholesterol" is like calling an ambulance en route to an patient a "bad ambulance" and an ambulance en route to the hospital a "good ambulance".

If we are to listen to the experts, we are expected to believe that the liver is actually manufacturing, using, recycling and re-using a compound, within the body, who's sole purpose is to give us a heart attack! Seems unlikely to me...

In relation to cholesterol, there are however a few parameters that do matter.

There is good evidence to suggest that the ratio of LDL to HDL is important. Not the actual numbers that you hear quoted by some doctors and dietitians, but the ratio.

With this fact in mind, lets look at something like butter. Yup, good old tasty, natural, saturated fat, butter. Yes it raises LDL cholesterol, but it raises HDL cholesterol as well. So the effect on our bodies is, at worst completely neutral (except for all the positive nutritional effect of course). One might even be so bold as to suggest butter could reduce coronary heart disease risk. But increase?  Nope, sorry, it just doesn't. The same for all natural fats that man has chosen to leave well enough alone!

The other factor that is extremely important is molecular size.

"Small, dense, LDL" are the real bad guys. These proteins can pass more easily into the arterial wall, where they can build up to form fatty plaque deposits. Normal LDL then joins the party in an effort to mop up the rancid, oxidised proteins and a type of scar tissue forms causing an obstruction of the blood vessel and all of  the consequences thereafter. This is most probably where LDL gets its bad rep - but it's just trying to do it's job.

Conversely, large fluffy LDL (as it should be) - causes no such problems. Their particle size means everything keeps flowing as nature intended and cholesterol can go about it's business of keeping us alive!

Ok, so small, dense LDL are the bad guys - but what causes it??

Well, as with most things, you can blame your parents as there is a genetic pre-disposition to have small dense LDL. An active lifestyle will reduce the risk - good news for us athletes!

But diet has a BIG effect and hopefully you can all predict where this is going.....

It's not a diet high in saturated fats that causes small, dense LDL but......

You guessed it....

A diet which is high in refined (high GI) carbohydrates and high in Trans Fats (fats that man has meddled with)!

Is that the sound of a penny dropping?

I hope so!

So what can we learn?

Cholesterol is good - our bodies need it to function, repair and survive.

There is nothing wrong with "Natural" saturated fats. Butter, cheese, eggs, whole milk and yoghurt is all good!

A great "Universal" fat is coconut oil - I may do a mini blog post about this incredible food later - but, suffice it to say, it's now the only fat (along with butter) that I have in my house. I use it for everything from frying, baking, bread making to spreading on toast.

If you must use a vegetable oil - make it virgin olive oil.

The real bad guys are not natural saturated fats but refined, high GI carbs, hydrogenated vegetable oils and trans fats. These can cause an increase in small, dense LDL - which are the REAL precursor to Atherosclerosis and CHD - avoid them and ANY foods containing them!

So there we have it.

Myth busted...pass the butter!

Nutrition and Fat Facts!

I've been meaning to write a blog entry about a subject which I am very passionate about right now...

Nutrition.

As athletes, I think we all realise that nutrition can play a huge role in performance. This becomes even more relevant in ultra endurance events like Ironman and beyond.

Think about it... We can all race at certain (comparatively fast) speeds over Sprint and Olympic distance, but we have to slow things right down for Ironman. In fact, I'm sure we'd all agree that none of us are going "that fast" in real terms during an Ironman and most people's Ironman marathon pace is well short of what they could maintain for a straight marathon.

So what is the limiting factor?

We've done the training. In IM we are not racing nearly as quickly as we are capable of in other distances and we've trained our bodies to cope with the various physical demands we subject our them to on race-day (impact forces, climate etc). Having met and addressed all these issues, one limiting factor remains, and its a biggy....

FUEL!

Ironically, it's probably the most important and maybe even the most overlooked - certainly when viewed as part of your training regime.

The rate at which you can fuel your muscles will have a greater impact on ultra endurance performance than almost anything else (assuming you've done the training!!).

We have a huge supply of energy which we carry around as fat, both beneath the skin (subcutaneous fat) and within the muscle known as "Intramuscular fat" or "Intramuscular triglycerides" (IMTG). The energy contained within these supplies is abundant - even in the leanest of athletes. "Training" your body to metabolise fat for energy at a high rate is the secret to unlocking your Ironman potential.

The master of this science was surely Mark Allen who, legend has it, could run at 6:00 per mile pace for an Ironman marathon metabolising fats alone!

A well designed nutrition plan can turn you from a "sugar junky" into a "fat burning machine" - essential for Ironman performance. At the same time it will also improve recovery, increase training quality, regulate energy levels, boost immune health and reduce disease risk (to name but a few additional benefits).

Worth saying here that by "Nutrition Plan" I mean a way of eating FOR LIFE. Every day, during training, after training as well as specific feeding during races. It's not something you "dip into" now and again. And it's certainly not something you should only give consideration to on race day. It's a commitment for life - but not one that needs to be all that difficult, or unpleasant, to achieve - quite the opposite in fact!

It's also worth saying, that the points I want to make, while perhaps directed towards "sporty people" are just as valid for the general population - maybe even more so! They just need to be tailored to suit your own energy needs.

I must also quickly mention my sources. Most of what I am now learning is a direct result of my involvement with Martin MacDonald, a Performance Nutritionist from Loughborough University. Martin has bucked the "main stream" in his search for the real facts regards performance nutrition. It is Martin's mission to debunk the many nutritional myths that are so often touted by businesses selling crack-pot diets, the media, Government Agencies and even the medical profession! Martin's results, with many high profile clients and elite sports people, speak for themselves and I consider myself very lucky to be in his care. I have gladly become one of his foot soldiers in this battle against nutritional bunkum and hypocrisy!

I can highly recommend Martin's Site. There is an abundance of information, Martin's own blog and a brilliant and active forum...

It's all cutting edge, and it's all free - Martin just wants people to know the truth!

Mac Nutrition



So, lets start with some basics....

Your body needs a certain amount of energy to function and we get this energy from the food we eat (and stuff we drink).

Even at rest, you need energy to "power" all your body's vital functions and it's organs. This includes breathing, circulating blood, adjusting hormone levels, growth, repairing cells and brain function - all pretty important stuff wouldn't you say! This amount of energy an individual needs every 24 hours, just to do this, AND NOTHING ELSE, is known as their "Basal Metabolic Rate" (BMR).

You can get a good estimate for yours here...

BMR calculator

The importance of fuelling these "life sustaining systems" is the precise reason why you would be very ill advised to ever reduce your calorie intake below your BMR. Don't do it!

Your body needs this energy - it can't do without it! In simple terms, it's like expecting your car to run without fuel - it won't and nor will you without adequate calories to meet you BMR requirements.

Sadly this is precisely what is advised by so many fad diets. Shakes, soups, bars whatever - they are not clever...it's simple calorie restriction (and profiteering). Worse still, these very low calorie levels are often achieved by a dramatic reduction in dietary fat intake (as fat is very energy dense) and are inevitably sub optimal in terms of "nutritional value" to boot.

Thankfully, our bodies have evolved over millenia to cope with calorie restriction or "famine" as some might like to call it. "Beta Oxidation" is the process by which the body can utilise it's own fat stores to produce "ketones" which the body can, in turn, use for fuel. The body goes into state known as "Ketosis" - a phrase you may well have heard about in relation to "Atkins" type diets (low cal / low carb).

There is no dispute, beta oxidation happens and it can lead to people losing large amounts of weight. Unfortunately the body is designed to hold on to it's fat stores - they are very precious! The body would rather "slow things down" first before resorting to beta oxidation. So your BMR slows - you now need fewer calories at rest and some of the "less essential" bodily functions start to shut down. Hair, skin, nails, hormones, energy levels and brain function all suffer.

You know the look - I call it "low cal chic". Pale, dry, papery skin, scraggy hair, broken nails, sunken eyes and diarrhea? And that's just the less serious stuff! Is it any wonder the body starts to fall apart when it needs maybe 1500 calories "at rest" and some crash diets restrict calorie intake to ridiculous levels like 500 cals per day (and still expect you to go about your daily activities and a trip to the gym!)

Another point worth mentioning here is Insulin. We've all heard of it. It's what regulates how your body deals with carbs and fats (more on this later). In simple terms - a healthy metabolism responds to very small amounts of Insulin - in other words, it is "sensitive" to Insulin - this is a good thing. Trouble is, a lifetime of poor nutrition and eating refined carbs can completely screw your body's sensitivity to Insulin. More Insulin is required to achieve the desired carb regulating effects which in turn increases the bodies fat storing potential. Individuals who's metabolism is screwed (or sub optimal) will struggle to loose weight through simple calorie restriction alone.

This effect was illustrated by a study I read recently, where lab rats were "overfed" and their Insulin sensitivity manipulated through the administration of Insulin injections. Not unsurprisingly, these rats became very, very fat. The feeding was then stopped completely and the rats were essentially starved. The Insulin injections, however, continued. One would imagine that the rats, in the absence of calories, would "tap into" their now abundant fat stores right?

Wrong.

They simply starved to death and just died very, very fat rats. Big old fat stores still very much in tact.

Anyway, I've wondered off track....Where were we?

Oh yes....so if you want to loose weight (fat mass) reduce calories by all means - but nothing lower than your BMR please!


So we understand the energy needs to meet BMR - but what about everything else? We all walk about, climb stairs, (some more than others), some have physical jobs etc etc. These activities also require energy. The energy demands of these activities, combined with the energy demands to fuel your BMR create your "Non-exercise activity thermogenesis" (NEAT). This is quite simply, the energy needed for all physical activities other than "sporting like exercise".

So lets say everything is tickety boo and you simply want to "maintain" your weight, you should consume enough calories to meet your "NEAT"..... pretty neat hey?

We'll talk about training in just a moment, but for the time being, lets stay focused on your "NEAT needs".

So where should these calories come from and does it really matter? Well yes it most certainly does! These calories should come from a variety of sources. For the purpose of obtaining calories, the ones that matter are Carbohydrates, Fats and Proteins. Lets just make one thing clear. It's ok to eat ALL these types of food. But what is certainly up for debate is the relative proportion of each food group.

Recommendations dating back to the 70's suggest a shift towards a carbohydrate rich (60%) low fat (20%) diet. It was suggested (and still is in more recent recommendations) that this is a far healthier way of eating and would lead to reduced levels of obesity and reduced rates of killer diseases and Type II Diabetes.

In reality, over the last 30 years, the opposite has happened. Even though a shift toward this type of diet has occurred, obesity, heart disease, and diabetes are all on the up. In fact statistics took a marked swing skywards since general populations started increasing intake of (mostly refined) carbohydrates. These dietary recommendations are completely unsubstantiated. They are not based on scientific fact and there is precious little (if any) evidence to support them.

Ever wondered if it makes sense to advise a shift away from fats and proteins, both essential for life, to carbohydrates, which the body has no biological need for whatsoever? I don't want to get too bogged down in specifics, but this video (all 5 parts) is well worth a watch and should leave you in no doubt that we have been sold a pup by Governments and food advisory groups.

To cut to the chase - A better ratio of food groups might be in the order of 30% Carbs, 40% Fat, 30% Protein. The figure that will jump out here for most people is 40% Fat. Please understand. Eating fat does not make you fat! Eating refined (high GI) carbs does!

Starting with fat, forget what you've heard about fat (particularly saturated fat) and heart disease. Again - there is a complete lack of evidence to support the link (Watch the videos above if you haven't already). The fats to avoid like the plague are those that man has "meddled" with (Man Made Trans Fats are the worst!).

Your fat intake should come from oily fish, nuts and seeds, and dairy (whole milk please, preferably un-homogenised). For cooking, baking or spreading you can't beat Coconut Oil (Virgin) or good old fashioned butter. If you must use a vegetable oil - stick with olive. Never use vegetable oils, margarine etc.

Butter and coconut oil etc are natural "food" products with nutritional value. Margarine is not natural and it's not a food. It has no real nutritional value. It's chemically closer to a lubricant than anything you should be eating! I plan to write a blog entry dedicated to fats (my new best friend) so I'll stop there on fats for the time being.

Proteins are best derived from animal sources though high quality protein can be derived by combining non-animal sources such as nuts, beans and pulses etc. It is however much more difficult to obtain a "full" protein with all the essential amino acids from non animal protein. As for meat,quality really does make a big difference. Words to look for are "organic", "free range" and "grass fed". If the animals were fed crap while they were alive, you'll just end up sharing in their misfortune!

Finally carbs. They are not evil - well not completely any way. They have their place in a healthy diet - particularly the diet of an athlete. As mentioned previously, around 30% of your NEAT needs can be met with carbs, but try and keep the sources low GI (below 55) as these foods have less of an affect on blood sugar and therefore Insulin (the fat storage hormone!).

Brown rice, Bular Wheat, Spelt or Rye Flour, whole meal pasta (cooked aldente) quinoa are all good "staples". Fruit is also very much on the menu, but best to stick to berries, plumbs, cherries, black grapes, pears and apples.

Also think about when you eat carbs. This is key. Consume them if you are training in the next few hours or after training to re-fuel but hold the carbs if you are not training for a while. For me this is midday, when my lunch is carb free (but high protein / fat).

Finally fill up on green leafy vegetables as often as you can - every meal if possible, though I accept that Broccoli for breakfast might be pretty hard to stomach for some!

The other point where carbs enter the equation is during long training sessions and post training. Here it's just a simple case of meeting the needs of the particular session. 1g of carbs per kg body weight per hour is a good place to start, but again, there is no reason why some of these energy needs can't be met with fats.

Re-Fuelling after training should occur as soon as possible. Ideally within 20 minutes. Your carbs at this point should be HIGH GI (contrary to everything I've been saying). Combining high GI carbs like Dextrose with a high quality whey protein supplement will create an insulin "spike" (in this instance desirable) to really kick start the recovery process and maximise training adaptation. I'll go into detail on this another time! Just a word or warning - immediately post training fats are to be avoided. Particularly if you are consuming high GI carbs to spike Insulin. For that reason, biscuits, cakes and chocolate should definitely be avoided at this time!

I kinda glossed over weight loss earlier, as this was not meant to be the focus of the blog entry. But to finish, if you want to loose weight, calorie reduction is required. However, NEVER reduce intake below your BMR. Keep the proportions of food "type" the same. If anything, reduce carbs, but never fats. Then it's a simple case of aiming for something in the order of a 500 kcal energy deficit per day, to affect a healthy rate of weight loss of around 1-2lb per week.

I hope I've inspired you all to look a little bit at your diets. I'll leave you with a personal observation.

Since working with Martin, my diet and calorie intake have been optimised to regulate energy levels, fuel my training sessions and shed body fat. I'll be the first to admit, that I'm naturally a bit of a bean pole, but I did have a few stubborn kg to get down to my ideal racing weight of 70kg. (it's even harder to loose weight when you don't have much to loose!).

My carb intake has been reduced and my dietary fat intake has increased by 200% yet the 2kg of excess body fat has gone! I'm running and biking faster than ever and have yet to catch a cold this winter. Oh yes and my hair has never looked so glossy!

Happy days!

So what does 2011 hold?

Ok, so just a little more background before we get into some more useful stuff...

"What are my plans for 2011" I hear you ask?



Ok, I didn't hear that, but I'll tell you anyway!


The Tri season is still a long way off of course but I have not been resting on my laurels. I tend to take the pressure off myself during the off-season. I train a lot on "feel" and really mix it up. At this time of year, I spend a lot of time listening to my body. I train how and when I fancy. I also try to address some of the weaknesses that I identified in 2010.


I try to avoid a huge amount of structure this time of year - again, keeping the pressure off. I believe "getting all serious" this time of year can cause a lot of stress (mental as much as physical). By the time the season comes round, you often see atheletes "burned out" from getting too serious, too soon.


Don't get me wrong, I'm not just sat on the sofa eating cake! I'm getting out every day - often twice and am conservitively racking up about 10 - 12 hours each week. Modest by many IM athletes standards - but hey I'm a busy boy!


At the mo' it's strength and endurance for me. So long off road runs and fun on the MTB (plus road miles when I really have to!)


However, I truly believe that completely negleting speed in the off season is a big mistake so I am still getting in tempo runs, intervals, horrible turbo sessions and hills. How many athletes spend the winter "getting the miles in" only to find themselves, in their first race effort of the season, wondering where all their speed went!

I'm a racer at heart though, so I've been packing those in as well. MTB Trail Quest races and an active season of Cross-Country (North Mids League and County Champs)

Leicester County Cross Country

 


The Local Road League got underway with the Barrow 6. I guided my pal Haseeb for that. Haseeb is a phenomenally talented blind triathlete. We flew round in 35:42. My heartrate was a steady 152 BPM which is a good 5 beats below my normal Half Marathon HR - so that all bodes very well.

Haseeb and Dunc at the Barrow 6 mile Road Race

Hasseb is also going for a fast time at the London Marathon. He's asked me to guide him. Works for me! I've always struggled with Spring marathons, just because, when run hard, they can take a lot out of you and can leave you needing about a month of pretty serious recovery - just when you should be getting ready for the Tri Season! At least by guiding Has' I may be able to stay a little more inside my comort zone. Not much though....the guy wants to smash 3 hours!

So there's my focus for the spring - Thanks Has'!

Few short term goals....

I have a Trail Quest this weekend in the Peak District, that I'm hoping to smash. I know the area pretty well, so that should help.

I'm then actually off to Morzine for a long weekend on the Snowboard. Hope to get some running in the Mountains while I'm out there!

In March I have a 21 mile fell race in Edale coming up and the Ashby 20 mile road race, where I will most probably guide Haseeb and test our pacing for London.

Claire, Myself and a group of our bestest mates have a cheeky little trip planned to Mallorca in April / May to find some sunshine and mountains.

On our return, with our new found bike legs, we'll be taking on a few sportives, including the Midland Monster and the awesome Fred Whitton

GULP!

 

Once the Tri season gets under way. I'll be picking my races quite carefully. I'll be needing some serious bike and run strength for the Norseman, so plan to tackle a few tough middle distance events. "Day in the Lakes" has been entered and a few other are "on the radar".


So the "biggy" is Norseman - more on that later. Think it deserves a blog post of it's own! I may round the season off by joining Claire at Challenge Barcelona but we'll wait and see how the piggy bank looks!


Stay fit and well guys...




Dunc

So who am I?

Well it's a question we all ask ourselves every once in a while...

We are moving from modernist calculation toward postmodernist simulation, where the "self" is a multiple, distributed system...

But I've no idea what any of that means so we'll just have to make do with a little of my history!

I grew up in the south of England. A skinny beanpole. Referred to, affectionately, by my politically incorrect father as "Oxfam body".

It was in Salisbury that I went to school where I soon discovered that I had a real aptitude for kicking a football in every direction other than the one that was intended. Since football was a sport my school was famous for - it offered little in the way of alternatives. It seemed academia was my only real option - so I immersed myself in more scholarly pursuits.

However, I quickly discovered, that by acting the fool during "football", I would be "punished" by being made to run around the football pitch for the duration of the lesson. Something I rather enjoyed and certainly a fate far preferable to having cold, wet, footballs kicked repeatedly at my head by the big boys.

So the joy of (and less ineptitute for) running was quickly discovered.

I also enjoyed swimming and hacking around the Wiltshire countryside on bikes that had been mackled together in the shed - clearly a Triathlete in the making!

In actual fact it was Martial Arts that really started my love for being physically fit. I still believe that it was the most fantastic grounding for a young kid. Discipline, a strong work ethic and the ability to take a regular beating (and keep coming back for more) were all fostered at the Salisbury Kung-Fu club over a 6 year period. I can still do press-ups on my index fingers!

It was around 1988 that I first heard about Triathlon and met up with a lively and infectiously enthusiastic chap called Dave Cerqua who had just started a Tri Club in Salisbury.

Triathlon seemed suitably wacky and left field (and didn't involve kicking a ball) so I signed up for my first event, the Swindon "Try a Tri" day, in the Spring of 1989.

I seem to remember finishing 13th, riding my Dawes Horizon touring bike and running in my Dunlop "Green Flash". Beaten in a sprint finish by my Mum, supporting from the side, taking photos (as she still does to this day!)

I was bitten by the bug and I haven't missed a Tri season since!

So, 20 odd years later, from Salisbury, to Leicester via Loughborough Uni, I have raced all over the world at all distances up to Ironman and feel truly privileged to have been involved in our great sport since it's early days in the UK.

My aspirations have always been modest. Perhaps lacking the "tools" to ever make it at the top level, I have always focused my efforts on Age Group racing. This approach has also offered me the opportunity to embark on the more esoteric races often "off limits" to the pro's - Marathon from Everest Base Camp anyone?

I have represented the GB AG team on a few occasions including Manchester, Lausanne, Nice and have won a little bit of silver (Plastic) ware along the way...

Supported by my wonderful Triathlete wife Claire and a bunch of brilliant mates, I continue to search out new races and new life experiences.

This years challenges are the Norseman Tri and maybe Challenge Barcelona, something I hope to blog about in detail later on. I'm also hoping to continue supporting Leicester Tri's ace (blind) Paratriathlete Haseeb Ahmad during his 2011 campaign.

It's gonna be a fun year - watch this space!

 

The Triathletes Guide to the Galaxy...

As Douglas Adams wrote in the opening paragraph to his brilliantly funny book..

"Far out in the uncharted backwaters of the unfashionable end of the Western Spiral arm of the Galaxy lies a small unregarded yellow sun.

Orbiting this at a distance of roughly ninety-eight million miles is an utterly insignificant little blue-green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea."

So, as one of the aforementioned "ape descended life forms" inhabiting this "insignificant little blue-green planet" what is my blog going to be about?


Well I'll tell you what it won't be..

It won't be anything highbrow or earth shattering!

In reality it'll most likely be a load of old nonsense out of which you ,the reader, might hopefully be able to discern the odd snippet that might prove useful (but I'm not making any promises).

Hopefully, together, we might learn something. Even if it's just a recipe for a really good flapjack or a tip for how to get Powerbar off your top tube!


I should say - these will be my ramblings from my own little world. I'll do my research where possible but most of what I say will be based on my own experiences and those of experts I trust and respect. Use the information that follows at your own risk!

I'll aim to include blog entries on anything that I might think my fellow swimmers, bikers, MTBers, runners and lovers of life might find interesting.


Hopefully, I'll talk about training, racing, kit, nutrition and a bit of what I'm up to when I'm not doing any of that stuff!


I hope you find it informative - or at least entertaining. 


Who knows, with a bit of luck, we might go somewhere to discovering the "Triathlete's Meaning of Life"....


I'm fairly sure it's not 42....
