Race Day Nutrition (Part Four) – Marc Laithwaite

©iancorless.com_MDS2015Day1-9809

So last week (part three HERE) we discussed carbohydrate absorption and the role of insulin, this week, we are going to look at how to take foods on board whilst competing, to avoid stomach problems and maximise performance.

I’m having issues getting energy, what’s the solution?

Your stomach and gut acts a little like a sieve. If you pour water into it, the water passes straight through without any problems. If you pour a milkshake into the same sieve, it will pass through, but will take a little more time and will slowly drip. If you throw solid food into a sieve, it stays exactly where it is. The only way to pass solid food through a sieve would be to mix it up with water and make a thin enough solution, which could then start to drip through.

The solution which enters your stomach, is therefore very important in terms of performance. During endurance events, we eat and drink to get energy, but if the food sits in your stomach, then you aren’t actually getting any energy into your bloodstream. Not only are you receiving less energy, you are also likely to get some kind of stomach problems.

Isotonic is just the tonic

Isotonic refers to a solution which is a similar concentration to fluids in the body. Solutions of 7% are generally referred to as isotonic, this means that 7g of carbohydrate in 100ml of water is isotonic. You can count grams and millilitres as the same thing, so the calculation is simple, 100ml / 7g = 7%.

Drinks bottles generally come in 2 different sizes, 500ml and 750ml so based on the 100ml / 7g rule, the calculations would be as follows:

500ml water + 35g carbohydrate = Isotonic

750ml water + 52.5g carbohydrate = Isotonic

Some solutions are less concentrated than isotonic fluids. For example, water has no carbohydrate in it and no calories, this is classed as hypotonic (hypo = low / less than). Solutions which are more concentrated than isotonic fluids, are classed as hypertonic (hyper = high / more than). An example of a hypertonic solution would be a smoothie.

That’s fine for drinks but what about solid food?

Many athletes choose to eat solid food during their event. As stated above, anything which is above 7% solution is hypertonic. Therefore, all energy bars and solid food is hypertonic. This means that if you wish to absorb solid food effectively, you must add sufficient water to make a 7% solution. For example, a standard energy bar is approximately 50-60g in total weight. We said earlier that 7g in 100ml of fluid would be a 7% solution, so that means you would have to drink 7-800ml of water with each energy bar to make at isotonic solution (56g is 7% of 800ml). In ultra running events, there’s often solid food such as sandwiches at feed stations, so get into the habit of estimating the portion size, e.g. what does 60g of cheese sandwich look like! Eating sandwiches, pasta and cake can very quickly result in a large mass of food gathering in your stomach. As for gels, they work the same way. A single gel contains 20-30g of carbohydrate (you need to read the packet). A gel with 21g would require 300ml to make a 7% solution.

Why is solution an issue?

Taking energy bars, gels and other solid food provides energy, but you have to take a lot of fluid to create an isotonic solution in your stomach. If you fail to take sufficient fluid you will have a thick ‘hypertonic’ solution in your stomach which may not digest and may well lead to stomach problems.

Don’t forget the 60g per hour rule

As we’ve said in previous blogs, it’s unlikely that you can absorb more than 60g per hour of carbohydrate so eating too much food can have a negative impact upon digestion. Eating too much may lead to food gathering in the stomach and leading to feelings of bloating or sickness. The carbohydrate ‘maltodextrin’ seems particularly prone to doing this and all carbohydrate drinks and gels tend to consist of maltodextrin (pretty much every energy drink on the market is the same, it’s flavoured maltodextrin).

It’s known that when you get an accumulation of carbohydrate in the stomach, due to excess food intake, the body is forced to dilute the solution. The strong solution sitting in the stomach starts to draw water other parts of the the body, into the stomach, to dilute the solution and aid digestion and absorption. This action of drawing fluid into the stomach is termed ‘osmosis’.

It’s important to remember that if you do take too much energy, coupled with a lack of fluid, not only are you likely to get stomach issues, the energy will also fail to reach your blood stream and exercising muscles where it is needed. In simple terms, more food may provide you with less energy.

Practical advice:

  1. You need to stick to the 60g limit for carbohydrate intake
  2. A solution of 7% is not always attainable, aim for 10% as a minimum start point for intake:

60g energy powder + 600ml water per hour
60g energy bar + 600ml water per hour
60g of gels (2-3) + 600ml water per hour

  1. You can mix the above, e.g. 30g carbohydrate powder and 30g gels every hour, plus 600ml of water.
  2. Think about what’s the easiest to calculate and what the easiest to obtain during the event. Knowing how much energy is in drinks which are handed up at aid stations or adding your own powder on the go is not really feasible so gels and bars are often simpler to use and to quantify. In truth, you really have no idea what’s being handed up in the drinks bottles, so water is always the safe option.
  3. Feeding is easier when cycling compared to running, so if you’re doing Ironman triathlon, the bike feeding is critical to set you up for the run. If you’re running an ultra, the slower pace can help, but little and often applies.
  4. Little and frequent works best for digestion. A gel every 20-30 minutes or half a bar every 30 minutes is better than a full bar every hour. You still need to drink the correct amount of water to account for solution.
  5. Drinking water only with bars and gels has the benefits of ‘freshening your mouth’. Energy drinks, gels and bars can leave you with a constant sticky taste.

What about the food content?

There is circumstantial evidence to suggest that eating too much carbohydrate may also impact upon digestion and potential stomach problems. If you are prone to stomach issues, then gels with a higher fat content may well work best. There are some very scientific high fat gels on the market, mainly in the US, but if you Google for peanut butter flavour gels, that’s a simple option and you can easily get those in the UK. If you don’t like peanut butter flavour, there’s not much option!

The final step

Ok, so here’s your homework. Go and purchase gels or bars, which you intend to use for your event and take a look at the wrapper. What’s the total weight in grams of the product and what does the content add up to? Remember, a gel may have added water, so a 40g gel may contain 20g of carbohydrate. Don’t just use the actual product weight, you need to check the weight of the ingredients and use that as your gauge. Work out how many you will need and how often you will eat them. If your event uses specific products e.g. Ironman use Powerbar, it’s a lot easier to use these on the day and save yourself the hassle of carrying a lot of product.

Hydration?

That’s coming next week

©iancorless.com_MDS2015Day7-2789

The 30th edition of the iconic Marathon des Sables is over! What a race… we all knew that race director, Patrick Bauer would create something special and he did not disappoint.

Tough stages and the longest days had runners tackling 92km’s, the longest stage ever in the 30 year history of the race.

Rachid El Morabity (20:21:39) won the men’s race once again in true style and Elisabet Barnes (26:42:13) showed pure class in winning every stage of the ladies race. A race summary will follow.

Below is a selected portfolio that encompasses the 30th edition of the race. A full image gallery will be uploaded to iancorless.phtoshelter.com in due course.

Race Day Nutrition (Part Three) – Marc Laithwaite

©iancorless.com_TCC2015_Day4B-1685

Last week we showed you how to calculate the amount of carbohydrate used during cycling and running, in order for you to produce a structured plan for race nutrition. This week, we begin the process of looking at what and when to eat on race day and the first step, is to explain the basic physiology.

Missed part one (here) and part two (here)

Carbohydrates

Carbohydrates or ‘sugars’ are a prime source of fuel when exercising and unfortunately, as explain in previous blog posts, they are relatively limited. The term for stored carbohydrate is ‘glycogen’ and we store glycogen in the muscles (to use for movement) and in the liver (to supply sugar to the brain and maintain blood sugar levels)

There are different types of carbohydrates, but ultimately, they are all broken down to glucose as this is what we use as our prime fuel. When you eat or drink carbohydrate, it first goes into your stomach. We can’t absorb carbohydrates through the stomach wall, so they progress from there into the intestines and are absorbed through the intestine wall

The rate of absorption

The carbohydrates you eat are broken into glucose and pass through the intestine wall into the blood stream. Remember that in recent blogs, we’ve stated that the limit for this seems to be around 60g per hour of glucose. Depending upon the type of carbohydrate and how it is consumed (drink or solid food), the time taken for the carbohydrate to be broken down and absorbed will vary.

Many of you will have heard of the ‘Glycemic Index’. This scale was designed with diabetics in mind and it dictates how quickly foods are broken down and absorbed through the intestine wall. To measure the GI of a food is relatively simple (but complex at the same time). The process is to give someone a specific food, then take blood samples at regular intervals for the next hour to see how rapidly the blood sugar (glucose) levels rise.

The ‘GI’ scale runs from 1-100. Foods with a low score will take longer to reach the blood and give a more consistent supply (slow drip feed). Foods which enters the blood stream quickly, will give a more immediate spike in the blood sugar levels. Pure glucose has a score of 100 as that will lead to a rise in blood glucose more quickly than anything else.

The role of insulin

The reason why the GI scale is so important for diabetics, is the ‘insulin response’. A rise in blood glucose will lead to a rise in blood insulin, which is the hormone responsible for removing glucose from the blood and pushing it into the liver and the muscles.

Your daily diet should be made up of foods low on the GI scale. It you eat foods which are high on the GI scale throughout the day, this results in repeated sugar spikes and subsequent insulin spikes. Over time, your insulin will become less effective (overuse can lead to it becoming less sensitive to glucose). The reduced sensitivity can eventually lead to type 2 diabetes (insulin doesn’t work correctly). You may think, as an athlete, you are not susceptible to type 2 diabetes, but you’d be wrong. It is critical for you that your insulin works correctly, so you should be doing everything in your powers to ensure it does.

The secondary issue relating to insulin, is the impact upon fat metabolism. It reduces the amount of circulating fat by encouraging storage in fat tissue. In terms of your daily diet and metabolism, this has significant consequences upon weight loss and fat use. Constant spikes in blood glucose and insulin will reduce the amount of fat you metabolise throughout the day.

Are we discussing daily diet in this blog or race day nutrition?

Okay, I am going off track a bit, but I think it’s important to understand the foundations. As an athlete, you need a constant and balanced supply of energy to complete your training sessions and to recover quickly. Therefore, you should be eating to encourage a more stable metabolism and that is derived from low to moderate GI foods, NOT high GI foods.

So how does this work during racing?

  1. If you are racing an endurance event, you really need to ensure that you have a steady supply of glucose, without disrupting fat metabolism. A large spike in glucose and insulin, could inhibit fat metabolism, which means you’ll be forced to use more glycogen and run out more quickly.
  1. There are times when you may well need a rapid rise in blood glucose. If you have an extreme low point in the race and find yourself sitting on the road side, you may need an ‘instant hit’. Under such circumstances, you need the quickest glucose spike possible to get you back on your feet. At times like this, who cares about insulin!!

Here’s the thing, if you do scenario number 1 correctly, then you shouldn’t experience scenario number 2. The other issue is that products that are sold to deal with scenario number 2 (high energy, quick acting gels) are being used for scenario number 1. If you are half way through a 12 hour event and your energy levels are feeling relatively good, should you take a product which gives you an instant spike in glucose and insulin? Remember, we are aiming for a ‘constant’ and ‘balanced’ blood glucose level, we are trying to avoid blood glucose ‘fluctuations’.

So this blog is not what I intended when I started typing and none of the original planned information has made the page. Needless to say, this 4 part ‘race nutrition’ series is not going to be 4 parts.

A critical point to take away is that over the years of giving advice, we’ve found that the daily diet can have a huge impact upon training and racing performance. In particular, cutting out high GI foods can lead to a dramatic change in metabolism and enhance your fat utilisation.

Your homework for this blog is to take a look at the glycemic index. You’ll find this very interesting and you’ll probably find that many of the foods you presumed to be ‘sugar spiking’ are not and vice versa.

What if I said that Coke had a score of 60, whilst mashed potato AND jacket spuds had a score of 90 (that means mashed potato and jacket spuds can give more of a sugar spike than Coke!!)

You’ll notice that there is also something called ‘glycemic load’. This takes the volume of food into account e.g. you can’t compare a full jacket spud with a teaspoon of glucose as the volume is very different. Don’t worry about that for now, it’ll over-complicate the matter!

Take a look for yourself, and see what’s low and high. There’s loads of them on the internet, Google glycemic index table. Next week we’ll look at the foods you eat during the event. How can you manipulate the use of drinks, bars and gels to maintain a steady blood glucose supply and avoid the fluctuations that we have discussed above. See… I told you there was a point to this blog.

Until then, stay healthy.

Salomon S-Lab Sense 4 Ultra SG (Soft Ground) – Review

©iancorless.com_Sense4SG-9063

C’mon, GET A GRIP!

Oooooh grip! I love grip…. before you read anymore, I strongly suggest that you read my very recent review of the new Salomon S-Lab Sense 4 Ultra HERE

I loved the Sense 4 Ultra but I did say that due to the precision fit, 4mm drop and relatively tight toe box, it would not be a shoe for everyone! I suppose the same should apply here… it does BUT I do think that other factors come into play for the ‘SG’ version.

First and foremost, when running off road and when running in muddy, sloppy or technical terrain you most definitely need a shoe that is going to hold your foot, allow little or preferably no movement and of course be precise. That is the Sense 4 Ultra SG. So you see, although normally I wouldn’t say squeezing your foot into a shoe is a good idea, with a SG version it is acceptable based on two key principles:

  1. The shoe is not ‘too’ tight and in anyway causes discomfort, pain or unnecessary stress.
  2. You are not running for hours and hours.

If you fall into the above two options and you are thinking that the SG maybe or maybe not for you; it may well be worth a risk for the supreme fit, comfort and grip.

As with the Sense 4 Ultra (non SG) the new shoe has had thorough reworking taking into consideration much of the feedback not only from everyday runners like you and I but also the elite Salomon runners such as Kilian Jornet.

©iancorless.com_Sense4SG-9068

SG stands for Soft Ground and as such, this shoe is all about grip when it’s needed. So, for many, the Sense 4 Ultra and Sense 4 Ultra SG go hand-in-hand and I think it’s fair to say that many will have (or at least wish for) both pairs of shoes.

©iancorless.com_Sense4SG-9072 The new shoe has been left alone in certain areas and tweaked and improved in other areas. Lets be clear, although it’s called SG it does make a perfect trail shoe for all conditions in my opinion. Admittedly, I wouldn’t want to run a pure hard trail in them but if I was mixing up dry trail, rocks, gravel, water, mud and a whole multitude of other surfaces, this is and would be my shoe of choice.

The Salomon S-Lab range very much follows the ethos of FAST and LIGHT but as the ‘Ultra’ name suggests, the shoe has a little more added to increase longevity and comfort. As with the Sense 4 Ultra, cushioning is 9mm and 13mm with a 4mm drop. I keep saying it but 4mm drop is not for everyone so don’t be tempted to use this shoe just because Kilian and the rest of the team use it… be sensible with shoe drop! The Fellraiser or Speedcross may be better options for you?
©iancorless.com_Sense4SG-9081

The SG upper, like the Sense 4 Ultra has been revised. The fit has been tweaked with additional support added to the mid foot. Additional room has been added to the toe box but it’s marginal in my opinion. Sensifit has also been tweaked and the mapping on the upper is now different and holds the foot more secure.

©iancorless.com_Sense4SG-9088

Sense 4 ULTRA on the left and the Sense 4 ULTRA SG on the right

Materials on the upper vary between the Sense 4 Ultra and the SG, the SG is more durable and arguably less breathable. The Sense 4 Ultra had additional toe box protection and the SG has even more added wich makes complete sense considering the shoe will be used in tougher terrain. If you read my Sense 4 Ultra review you will know how much I love Sensfit, Endofit and all the usual Salomon buzzwords. In a nutshell, for me, no shoe on the market fits as well as a Salomon Sense and I am inclusive in that statement; the Sense Pro, Sense Mantra 3 and so on all have that wonderful precise and secure hold. It’s the best! (If the shoe fits you)

©iancorless.com_Sense4SG-9094

The SG is obviously a shoe for the rough and tough and the tongue has been changed to provide added protection and security. The fit between the upper and the tongue has been re-designed to reduce any possibility of debris entering. The lacing system and lace pocket again make the Salomon Sense stand head and shoulders above other shoes. It’s reliable, logical, provides great overall tension and of course, what you don’t need is stored away. The obvious downside is that adjusting tension is very difficult. So you’d have to make a call if that works for you! Many have said to me, ‘what if the lace breaks?’ In all honesty, I have never had a lace break and I don’t know anyone else who has.

©iancorless.com_Sense4SG-9078

As with the Sense 4 Ultra, the SG has a complete overhaul of the outsole. The Contragrip lug pattern has been changed and the lugs are deeper to provide additional grip when the ground is soft and muddy but not so much grip that you cannot run on dry, hard or rocky trail. The compound has been revised and I noticed a difference on wet rock. The shoes have better bite. I said in my Sense 3 Ultra SG review (HERE) that although the shoe is called SG I wouldn’t necessarily say it would be my out-and-out soft ground shoe. The same applies here! I think the Sense 4 Ultra SG is an improvement on the previous model but if I just wanted a shoe for mud, I would potentially look at another option. Don’t get me wrong; this is not a negative comment. For example, Salomon make the S-Lab Fellcross and that would be ideal… the Sense 4 Ultra SG is designed for multiple surfaces, including soft ground and in those uses, they excel!

©iancorless.com_Sense4SG-9101

In Use

What can I say, the SG runs as well if not better than the Sense 4 Ultra. They do feel a little different and this is primarily down to the lugs on the bottom of the shoe. With the extra lug height, it does make the SG feel a little more cushioned, it may be placebo but I don’t think so.

Fit between the Sense 4 Ultra and SG is almost the same. No, it is the same. The only difference comes in the material used on the uppers. The ‘Ultra’ has a more breathable and lighter upper in comparison to the SG which is a great call by Salomon. One could almost say that the shoes are Summer (Sense 4 Ultra) and Winter (SG). Of course it’s not that simple, particularly if you run in the UK! We don’t have summers, so, they are both winter shoes ;-).

The toe box of the SG feels the same as the Sense 4 Ultra in use but does have more protection..

Running in the shoe is a dream. Foothold and protection is awesome. The shoe has plenty of flex and suppleness (especially after 3-4 runs) and the Endofit, Sensifit and Quicklace make the precision feel of the shoe shine. I really struggle to find any negatives. Grip in the heal area is brilliant and once on and laced up, you have no foot movement. Just whaT I want from a shoe that would tackle technical terrain.

The grip is definitely improved over the Sense 3. On my local trails I noticed improved grip on softer ground and transitioning between surfaces is seamless. Ironically, the SG does feel nice on the road but I don’t recommend too much, particularly if you want the sole to last! On wet rocks, pavement and tarmac the outsole noticeably provided a more secure and reassuring contact with the ground. Is it the best out there? No, probably not. But this outsole is designed for ultra and mixed terrain, soft ground just being one aspect. I’d have no problems with the SG being my ‘go to’ trail shoe for any race or training run.

On that note, is it really an ultra shoe, by that I mean could I run for hours and hours in it? No I couldn’t. I love the 4mm drop but for me, I think I’d need something a little more relaxed for real long stuff, a 6mm or 8mm drop version would be sweet. Lets be clear though, that is me being greedy. The Sense 4 is an S-Lab shoe and as such, it’s all about speed and efficiency. On the right feet, these shoes will fly!

PROS:

  • Light
  • Responsive
  • Grip
  • Fit
  • Black and red (my fave colours)

CONS:

  • Too tight for some
  • Expensive
  • I struggle for cons!

It’s always difficult reviewing a Salomon S-Lab shoe as to be honest; I find it very hard to find negatives. The negatives are more often than not based around the shoe not being suitable for some people because of width, drop and so on.

The same applies here! The Sense 3 Ultra and Sense 3 Ultra SG were both brilliant shoes and the Sense 4 incarnations of both shoes are better! It’s hard to believe but they are.

Weighing in at 260g for a UK 8.5 (true to size fit), the Sense 4 Ultra SG is without doubt one of the best ‘grip’ trail shoes I have used. I do wish that Salomon would make this ‘exact’ shoe with a 6mm or maybe even a 8mm drop.

©iancorless.com_Sense4SG-9060

As with the Sense 4 Ultra: the Sense 4 Ultra SG has OS Tendon, Profeet Film, dual density EVA, racing last, Quicklace, Sensifit, Endofit and a series of other notable technologies making this shoe the best 4mm drop shoe on the market… should the precise fit work for you!

Recent changes in the Salomon Sense range now make the Sense 4 Ultra (dry fast trail), Sense 4 Ultra SG (mixed trail) and the Sense Mantra 3 (road and trail) my shoes of choice. I keep going on about the Sense Mantra 3 (Here) but I think this is a great everyday shoe.

My final question is, will we see a new Sense Pro?

He must be CRACKERS! Part Two of an interview with James Cracknell

Crackers 2

In our next article we feature James’s experiences in the Marathon des Sables in 2010 and his tips for those taking part in April 2015 or planning to take part in the race in future years. His 2015 comeback plans include the Richtersveld Wildrun and the Badwater 135.

“It will be about me drawing a line after the accident as well and moving on. It will be nice to go back to Death Valley and put some demons to rest. I need to square the circle and move on. I don’t want my life to be defined by winning two gold medals. I don’t want my life to be defined by being the guy who got hit on the head by a truck! I refuse, I will choose my path and I will not be pigeon holed. I will create my path.” – James Cracknell

It’s game on at the Richtersveld Wildrun™

At the sharp end of this year’s 150km, 4 day Richtersveld Wildrun™ race will be three of Southern Africa’s best trail runners, an American ultra-running legend and a double Olympian gold medallist.

Bernard Rukadza and Katya Soggot will both return to defend their titles and will come up against the likes of South African long distance trail running champion, Thabang Madiba, American ultra-running legend, Nikki Kimball and global adventure extraordinaire, James Cracknell.

Mens Four Medal Ceremony

The friendly Cape-based Zimbabwean and current Richtersveld Wildrun™ record holder, Rukadza, comes off his second straight victory at the ProNutro AfricanX with teammate, AJ Calitz and will be confident that he can defend his Richtersveld Wildrun™ title. He put in a dominant performance at the inaugural event in 2014, winning three of the four stages and thus goes into this year’s event with a distinct advantage over Madiba. “I know the route from running it last year and I definitely want to win again. I always want to push and improve my time and am looking forward to racing Thabang. He’s very good and it will be fantastic,” he said.

Gauteng-based Madiba, on the other hand, will be giving his all and plans to push the limits as he gains more experience in stage racing. He has set his sights firmly on improving his second place at the ProNutro AfricanX, but is philosophical on his approach to the Wildrun™. “Stage racing is one of the races that helps to find your strength in running. You learn to push while in pain and learn techniques to apply to survive all stages. It is only a matter of surviving and reaching the finish line. I’ve never done 150km in four days before and I’m super excited to give it a try. Life becomes interesting when you try new things and get out of your comfort zone. A win will be a big bonus for me but I’m looking forward to give all my best,” he said.

“What more can be said other than this is going to be one hell of a race! Bernard has been on fire in the Cape recently, winning everything from marathons to short Spur Trail Series™ events, but Madiba comes with the South African long distance trail champion label and arguably more endurance experience. I can’t wait to see these two trail heavy weights going head to head, solo, and in the magical Richtersveld desert,” said Owen Middleton, MD of Wildrunner – the events company behind the Wildrun™.

Also in the hunt, and sure to be nipping at the heels of Rukadza and Madiba, is second time Richtersveld Wildrun™ challenger, Filippo Faralla as well as British adventurer, James Cracknell.

Soggot vs Kimball

In the ladies field, Katya Soggot will be representing South Africa off the back of victories at the Spur Silvermine Mountain XL, Spur Cape Summer Trail Series™, Three Peaks Challenge, Matroosberg Challenge and fourth place at the Otter African Trail Race, to name but a few. Soggot’s continuous achievements will come in handy as she is up against three-time Western States 100 champion, previous Ultra Trail du Mont Blanc champ and current Marathon des Sables champion, Nikki Kimball.

Other top lady runners who are worth keeping an eye on, include the female winner of the 2014 Rhodes Ultra Trail Run and uber-experienced ultra-trail runner Karoline Hanks; third placed female at the Wildcoast Wildrun™ 2014 Harriet Cullinan; and second placed female at the 100km Cederberg Traverse, Georgina Ayre.

“Last year, the ladies race was very amicable, with Katya and Tracy Zunckel running together for a large portion of the time. This year will be so exciting to watch, with at least five really strong contenders for the title. Katya will be looking to defend her title, with the advantage of knowing the route and Nikki is certainly a tough challenger,” says Tamaryn Middleton, general manager of Wildrunner. “Karoline Hanks is also extremely strong and comfortable with self-navigation so is definitely one to watch.”

Soggot has said she has amazing memories from the Richtersveld Wildrun™ in 2014 and is ecstatic to go back again. “The magnitude of untouched wilderness, the comfort and welcome at every rest camp, and the elves who made it so. My feet touched where angels fear to tread. I never dreamt I would have the privilege to relive such an experience and I am overwhelmed with gratitude to Boundless Southern Africa and Wildrunner for the opportunity,” she said.

Since its inception in 2014, the Richtersveld Wildrun™ has had amazing support from Boundless Southern Africa and marketing manager, Roland Vorwerk was equally excited about the quality of racing anticipated. “The Richtersveld Wildrun™ route includes many of the Park’s most spectacular features, and includes trails that very few people get to traverse. We are looking forward to these runners experiencing the unique natural and cultural landscape of the /Ai/Ais-Richtersveld Transfrontier Park and meeting the communities associated with this innovative event.”

Race Day Nutrition (Part Two) – Marc Laithwaite

©iancorless.com_TCC2015_Day1-9778

So last week (Part One Here)we finished by talking about how many calories you use during an event and how to make a quick calculation of fat and carbohydrate contributions. To recap, we said:

80/20: If you are struggling to ride 50 miles / run 15 miles even when fuelling yourself throughout, then apply the 80/20 rule. That means 80% of your fuel is carbohydrate and 20% is fat.

65/35: If you can ride 50 miles / run 15 miles comfortably using fuel, then apply the 65/35 rule. That means 65% of your fuel is carbohydrate and 20% is fat.

50/50: If you can ride 50 miles / run 15 miles comfortably without using any fuel whatsoever, then apply the 50/50 rule. That means 50% of your fuel is carbohydrate and 50% is fat.

Let’s give ourselves a simple scenario. Tom is 43, weighs 82 kg and is racing Ironman triathlon, he falls into the 65/35 category and his main objective is to complete the event without major disaster and to run as much of the marathon as possible. When Tom is riding at his Ironman pace, he is using 820 Kcal per hour, so the calculation works like this:

Fat contribution:  820 Kcal x 35% = 287 Kcal

Carbohydrate contribution: 820 Kcal x 65% = 533 Kcal

Step 1: Discard the Fat

The calories which come from fat do not need to be replaced, even the leanest athlete has ample fat stores for the longest endurance events. Step 1 is therefore to discard the Kcal from fat and focus on the carbohydrate contribution. Carbohydrates is the fuel which must be replaced!

Step 2: Focus on the carbohydrate

For Tom, our calculated figure is 533 Kcal of carbohydrate per hour, so this is our target to replace during the ride. It’s often easier to work in grams as most foods are also measured in grams. Each gram of carbohydrate contains 4 Kcal, so we calculate grams of carbohydrate as follows:

533 Kcal per hour / 4 = 133 grams per hour

Step 3: Apply the maximal intake rule

You may remember from the last couple of weeks, we discussed that the maximum amount of carbohydrate you can take during exercise is 60g per hour. Tom is using 133 grams per hour (just to clarify, that’s not excessive and is realistic). If the maximum Tom can take is 60g per hour, that means there’s 73 grams (133-60) that he’s losing and can’t be replaced every hour.

Step 4: Work out the race total

Tom’s bike time is estimated to be 6.5 hours. If he’s losing 73 grams of carbohydrate per hour which can’t be replaced, what does that add up to over the total bike ride? Well, the calculation is simple: 6.5 x 73 = 474.5 grams. That means that Tom will lose 474.5 grams of carbohydrate, which he can’t replace, by the end of the 6.5 hour bike ride.

Step 5: Work out your time to collapse

The big figure missing here is the actual amount you have got stored in your body, is losing 474.5 grams a big problem? The average human stores 400 grams of carbohydrate stored in the muscles,  and 100g is stored in the liver. There’s also approx 25g circulating in your blood at any given time. For the astute amongst you, the problem has already struck you squarely between the eyes. Tom, sadly, will not be running the majority of the Ironman marathon.

Does this happen in the real world?

Definitely, take a look at the photo below. This is some data for an Ironman athlete taken this week, male veteran, approx 68 kg with a long history of endurance competition. There’s 12 minutes of data on the screen, the first column shows the power output (watts) and the third column shows time in minutes. Prior to this the rider warmed up for 10 minutes at 100-120 watts. Now look at columns 11, 13 and 14 on the far right hand side, they show Kcal per hour, fat% and carbohydrate%. Consider that 120/150/170 watts is not high intensity, despite that and the previous warm up, you can see that the carbohydrate use is very high. Take into account that our athlete is only 68 kg and that Kcal per hour will be greater in larger athletes.

IMG_0534

Would these fugures be similar for running?

Yes, pretty much. The Kcal usage is slightly higher when running at a similar intensity, but the fat usage tends to be a little higher also. I’d suggest that the fat usage is slightly higher as running requires less ‘fast twitch’ fibre contribution, cycling requires a cretain amount of ‘stregth’. Running intensity also tends to be a bit more consistent. Cycling can be hard on the uphill and then rest and freewheel on the downhill, but running is less so.

Should Tom withdraw his entry right now?

Hang on… we know that people can ride the full Ironman bike and then run the marathon. We also know that people run 100 miles, so there’s got to be a catch, these calculations can’t be correct. Will Tom be completely depleted of all carbohydrate even when taking in the recommended 60g every hour?

No, indeed he won’t and the calculations are not so clear cut as above. Your body is pretty clever so it will make some changes along the way to help you out. Throughout the event, your metabolism will switch, so it’s reasonable to suggest that by the time the bike has ended, 50-60% of Tom’s energy will come from fat, rather than the 35% contribution at the start point. That means he’ll only be using half the amount of carbohydrate every hour, compared to when he started.

That’s good right?

In some ways yes it is, it’s saving your carbohydrate stores by halving the amount used every hour. But you need to consider why this change occurs. Your body switches to use a larger amount of fat because it’s ‘RUNNING OUT OF CARBOHYDRATE’ so whilst every cloud does have a silver lining, let’s not look too positively on this change.

As most people struggle to metabolise fat, having to rely upon it will lead to a drop in pace and performance. If we continue our theme of ‘clouds and silver linings’, at least the slower pace means you will be using less Kcal per hour (slower pace = less energy required) so that also helps to reduce the amount of carbohydrate required.

Is anyone else getting concerned here or is it just me?

It’s ok, there is an answer. The 2 key areas for improvement are economy (Kcal per hour) and substrate ulilisation (fat or carbohydrate). If you are aerobically fit, you will be more economical than most people. In fact, for endurance performance, economy is perhaps the most important thing. We can define economy very simply as ‘how much energy do you need to ride or run at any given speed?’

If you take your unfit pub mates for a run, you may well trot along at 8 minutes per mile and hold a comfortable conversation. Your mate on the other hand, may be breathing like a bulldog in a hot car, blowing out of most parts of his body. He will be using far more energy, require far more oxygen and use far more calories. People are like cars, some can go a long way using only a small amount of fuel and some require a regular filling due to their poor economy.

The second thing to consider is substrate utilisation. This simply refers to the relative contributions of fat and carbohydrate towards your total energy need. We’ve discussed this above and in pretty much every blog in the last 6 weeks, so hopefully you’re already familiar with this concept. If more of your energy comes from fat, you’re less likely to run out of carbohydrate. The best athletes in the world require a small amount of energy (Kcal) to ride or run at race speed. If a large chunk of that energy requirement comes from fat, their total carbohydrate use is very small indeed.

The new Tom… we can rebuild him

By making changes to Tom’s training and diet, the new version arrives for the Ironman triathlon using only 700Kcal per hour and 55% is being provided by fat. A quick maths calculation reveals the following:

1. He’s using 315 Kcal of carbohydrate per hour on the bike, compared to the previous figure of 533

2. With his intake of 60 grams per hour (240 Kcal), he now only has a deficit of 75 Kcal per hour compared previously with 292 Kcal (73 grams)

3. As a consequence, Tom runs the whole marathon and Tom becomes a LEGEND…..

Do you want to become a legend? If so, do the calculations and work it out for yourself, then let’s go forwards from here.

He must be CRACKERS! Part One of an interview with James Cracknell

Crackers 1

In a previous life, James Cracknell spent too much time mucking about in a boat with big blokes wearing too much Lycra. He was lucky enough to win gold medals at the Sydney and Athens Olympics. After that he stupidly rowed across the Atlantic and did a race to the South Pole (both filmed by the BBC).

 

After Antarctica he decided the cold wasn’t for him and entered the Marathon des Sables where he did okay and came 12th. At the time that was the highest place a Briton had ever come until Danny Kendall upstaged the Olympian.

James’s MDS progress was filmed by the Discovery Channel. This was followed with another film documenting a journey from LA to New York: cycling from LA to Death Valley running through Death Valley then remounting and cycling Route 66 to Lake Erie, rowing Lake Erie then cycling to New York and finally swimming to the Statue of Liberty.

 

Unfortunately James didn’t complete this journey as a fuel truck in Arizona hit him! Placed in a coma and a two-month stay in a Phoenix hospital, James was close to the edge. It’s been a long journey and one that is ongoing.
