Fuelling a World Record Attempt
Updated: Jul 7
On 26/27th June 2021, a team of determined cyclists set a Guinness World Record for the fastest cycling journey from Land’s End to John O’Groats (LEJOG) in a relay team format and here we talk about their fuelling strategy.
Essentially a team of 12 riders will take it in turns to produce 1-hour intense efforts, passing a GPS baton between them as they travel from Land’s End to John o’ Groats. The aim for the team is to maintain as high an average speed as possible and although they might be filled with enthusiasm and leg speed at the start of the challenge, fatigue will start to take its toll as the event progresses and it’s our job at TORQ to provide a nutritional strategy to help mitigate this. TORQ are not only supporting the riders with nutritional products and advice, but TORQ’s owner Matt Hart, TORQ’s Tri team manager James Emery and long-time TORQ Ambassador Mark Turnbull are 3 of the athletes forming the team of 12. TORQ’s Performance Director Marcus Willday is also supporting the team as a substitute and has a very high chance of needing to ride should an unforeseen mechanical occur. In short, TORQ are heavily invested in this project.
The fitness of the riders will be variable, but all have trained hard to achieve a minimum functional threshold power (FTP) of 285 watts (the power they need to hold for an hour) and some of the larger riders will be producing significantly more power than this. This kind of power output equates to over 1,000 calories per hour in energy expenditure and due to the intensity of the riding, many of these calories will be coming from carbohydrate. The body has a limited supply of stored ‘endogenous’ carbohydrate (around 2,000 calories), so it’s easy to see how after a couple of FTP efforts (and each rider will need to do 3-4), these stores are going to be very low indeed. What happens if a rider’s endogenous stores run dry? They will bonk, or hit the wall, which is when all of the power in their legs will disappear and if this happens to any rider during the attempt, the pace will slow and the World Record will be in jeopardy. To understand how and why we ‘hit the wall’ and why fuelling with carbohydrate is so important, please take the time to watch this really useful video:
As the video demonstrates, consuming carbohydrate during each FTP effort is going to be vital, because literally every gram of exogenous (energy product) carbohydrate consumed whilst riding is a gram that is spared from their endogenous stores and the more that is consumed, the greater the endogenous savings. Quite simply, the exogenous fuel source is burned in preference to the stored carbohydrate. There is of course a limit to the amount of carbohydrate the human body can absorb and use in an hour and this is where the formulation of TORQ’s energy products excel. Our 2:1 Glucose Derivatives:Fructose formulations are capable of delivering significant amounts of carbohydrate into the blood per hour and we have long recommended up to 90 grams of carbohydrate per hour via TORQ’s Fuelling System. Remember that’s 90 grams of carbohydrate (360 calories) that won’t be taken from the riders’ endogenous stores, leaving them less depleted at the end of each bout. This is effectively free energy that they can take forward onto their next effort.
Recently in an article written on this website, we revealed that more recent research has suggested that 120 grams of carbohydrate absorption per hour is likely to be possible using TORQ’s 2:1 formulation and although we have been naturally cautious with this advice up until now, this seems to us to be the perfect environment to recommend it. In practical terms, due to the nature of the exercise being carried out, there would be no obvious downside to each athlete consuming 120g of carbohydrate in the hour that they exercise. Endurance events typically requiring fuelling last for significantly longer than an hour, so consideration needs to be given to the amount of carbohydrate consumed hourly, because over-consumption over a longer timeframe would result in carbohydrate not being absorbed, leading to gastric distress. We have previously written an article on the subject of fuelling and avoiding gastric distress and one key message is not to over-consume. The benefit of this challenge is that the riders will only be exercising for around 1 hour and then they will get a decent sized break, so the risk of gastric distress is low – and if it were to happen, it can be easily combatted during the rest period, which we will discuss shortly. So, to be clear, the research suggests that 120g of carbohydrate absorption per hour is possible and the format of the event protects the riders from any potential pitfalls. As a caveat, should a rider struggle with this level of consumption, we would recommend that they revert to 90 grams of carbohydrate consumption on their subsequent effort, which is still significantly higher than other commercially available formulations are able to deliver.
Therefore, the recommendation to the riders will be simple (largely because the TORQ Fuelling System is simple) and that will be to consume 4 TORQ units (120 grams of carbohydrate) per 1-hour effort. Each TORQ Unit equals 30g of carbohydrate. To achieve this, the rider will be asked to consume 1 TORQ Energy Gel immediately before they start their effort and then another at 20 minutes and another at 40 minutes into the ride (that’s 3 TORQ Units). They will also have a 500ml bottle of TORQ Energy Drink on their bike, which they will be advised to consume in its entirety. 500ml of TORQ Energy is also 1 TORQ Unit. 4 TORQ Units in total. Should they choose to revert to 90 grams per hour (3 TORQ Units), we recommend 1 TORQ Gel immediately before they start their effort and one 30 minutes into their effort (that’s 2 TORQ Units), plus 500ml of TORQ Energy which they should drink in its entirety. 3 TORQ Units total. As this event allows the riders breaks between efforts, the nutritional recommendations can be clear cut like this, which is really helpful. Usually we recommend an adaptive strategy via the TORQ Fuelling System, because the level of hydration a rider will need is variable, but with this event there’s enough time between bouts to rehydrate if necessary. What the riders will only have one chance to do is get the carbohydrate in and they can’t afford to miss a feed.
We are not recommending consuming TORQ Energy Bars or Chews, because they are not practical fuelling products for these kinds of efforts – the fuel intake needs to be quick, slick and easy. TORQ Bars and Chews will be used during the break period, not on the bike.
There is a danger that some riders might think that moving from their aero position or letting up slightly to take on fuel is going to cost them valuable seconds and this could dissuade them from fuelling properly. The message we are firmly getting across is the need to look at the bigger picture – would you rather lose 30 seconds as a result of reaching into your pocket a couple of times to consume gels in the early stages, or risk losing minutes in time when you blow up spectacularly on effort 3 because you ignored the fundamental principles of fuelling?
That’s fuelling during exercise covered off, so what do the riders do in their downtime between bouts? The first product they will be consuming will be TORQ Recovery Drink. There’s a narrow window immediately after exercise where physiologically, absorption of carbohydrate is heightened in the same way that it is during exercise, so capitalising on this window of opportunity is very important. During the effort the rider fuels to provide an alternative exogenous source of carbohydrate to preserve their internal endogenous stores, whereas after exercise, the carbohydrate they consume is used to re-stock those stores. They are 2 completely different processes, but it should be quite clear how important it is to tackle both of them. The restocking of endogenous carbohydrate stores doesn’t stop with a recovery drink either, the rider will be encouraged to graze on high carbohydrate, low fat foods constantly during their downtime.
The other vital nutrient that TORQ Recovery Drink offers is protein. The riders will need to consume 20-25 grams of protein every 4-5 hours to maintain a positive protein balance to prevent muscle breakdown/facilitate muscular repair and the recovery drink provides one of those portions. Depending on how the rotations work for each rider (they are all slightly different), the recovery drink may be the only source of protein needed during the event. Riders with longer breaks between bouts will need to look at some sensible protein-based food choices too. If you would like to learn more about the role that protein plays in the human body and how important it is to athletes, read our Protein, Performance and 20-25g Protein Recipes article.
What we would typically call ‘normal food’ certainly has its place and will be encouraged during the event, but careful considerations will need to be made. Fat is the enemy on event day, so however much a rider is craving a burger or chocolate cake, these items are outlawed! Fat will kill any rider’s performance and it’s a simple concept to understand – fat blocks the absorption of other nutrients. That’s not to say that you won’t absorb the nutrients eventually, but dietary fat slows down the absorption so much that any optimal performance nutrition practices being followed will be negated. Not only this, but the gastric problems we were concerned about with regard to overconsumption of carbohydrate will be pretty much guaranteed and can’t be resolved quickly, if at all. To absorb the significant 90 to 120g of carbohydrate per hour required, the points of absorption in the small intestine need to be clean and clear and fat will block them. It’s like running the tap in the bath with the plug in – eventually it will overflow and overflowing in the context of performance nutrition means throwing up! We want the tap running, with the plug out. With the plug inserted, all the good stuff your body needs can’t get in, so it’s game over.
