Whilst many elite athletes have tested LCHF approaches, it has not gained a significant amount of traction at the top end of sport.

The latest study to address the issue was just published in the Journal of Applied Physiology by a research group led by Robert Jacobs of the University of Colorado Colorado Springs. Jacobs and his colleagues use real-world data to simulate the range of physiological characteristics seen in elite marathon runners and calculate how much carbohydrate they would need to successfully run a sub-two-hour marathon.

The exact amounts depend on a variety of factors including the size of your liver and legs, but on average the researchers estimate that elite male marathoners start with grams of glycogen and female marathoners start with grams. At first glance, this seems promising, because they calculate that a two-hour marathon should require grams of carbohydrate for elite men and because women are smaller on average grams for women.

Overall, you can use up about 62 percent of your stored carbohydrate during a two-hour marathon, leaving a substantial shortfall that you need to make up by drinking or eating more carbs. To make the numbers work for a two-hour-marathon, Jacobs and his colleagues calculate that an average elite male marathoner would need to consume 93 grams of carbohydrate per hour, while an average female would need grams per hour—significantly higher than the gram max in current sports nutrition guidelines.

We could run a similar calculation of how many carbs we would need to run back-to-back marathons in four hours, and that calculation would produce an astronomically high number, but the number would have no real-world meaning.

The limits of endurance depend on far more than carbohydrate supply. Still, Jacobs offers three arguments for why the two-hour-marathon numbers are worth taking seriously.

One is that recent lab studies have shown that humans are, in fact, capable of burning more than 90 grams of exogenous meaning from drinks or food rather than internal storage carbohydrates per hour. For example, a study published last year by Tim Podlogar, an exercise physiologist at the University of Birmingham and nutritionist for the Bora-Hansgrohe pro cycling team, fed cyclists grams of carbohydrate per hour and found that they were capable of burning just over 90 of those grams per hour.

The rest will be either excreted or stored for later use. Reaching this level of carb burning involved drinking a mix of glucose and fructose in a ratio of She also recommends reviewing food labels to determine total grams of carbohydrates in a product, as well as the specific ingredients e.

The available evidence suggests that, as was the hunch of the Boston Marathon researchers in , fuelling hard endurance efforts with adequate carbohydrate is still the best nutritional approach to maximising endurance performance that we currently have at our disposal.

With that being said, some selective and intelligent use of periods of low carbohydrate availability may be useful in training to drive enhanced adaptations and to make the most of fat burning abilities where they could offer an advantage Image Credit: Dale Travers ©.

Whilst I do firmly believe that fuelling with plenty of carbohydrate is critical to support high levels of performance and recovery around hard training and most endurance races, this is not the same as saying athletes should universally eat lots of carbohydrates AT ALL TIMES.

And, on a simple level, this may be very useful for weight loss, which can of course be performance-enhancing in some cases. Please see this blog on Relative Energy Deficiency in Sport RED-S for more information on why that needs to be approached with caution.

A highly selective rather than complete low-carb approach to fuelling centred around certain specific workouts or phases of training being undertaken in a low carb state could also be very useful for stimulating greater overall adaptations in muscles to endurance training and enhance subsequent fuel utilisation abilities.

Looking ahead, we can definitely hope for more research and field-based evidence to emerge in this specific area in the coming years, as this avenue of performance nutrition attracts more and more interest.

Early research into carbohydrate fuelling Check out this abstract for a paper examining the potential benefits of carbohydrate ingestion for athletes in How your body uses carbs and fat to fuel exercise The reason the researchers in Boston chose to give the runners candy and sweet tea during the event rather than bacon or butter was that, even back in the s, we understood that carbohydrate is the body's preferred source of energy during higher intensity exercise and that running out of carbs is a sure-fire way to induce premature fatigue.

But in the year and a half since then, very high doses of carbohydrate have become an emerging trend among elite endurance athletes. New science suggests that it really is possible to consume as much as grams of carbohydrate per hour, and some pros are reportedly even higher than that.
