You’ve probably come across discussions in the last year or so about the ‘high carb trend’ - taking very large amounts of carbohydrate during exercise, often well over 100g per hour. These levels are significantly greater than official sports nutrition guidelines, so what’s behind the trend? Is it based on new science, product marketing, or is it just another fad that will come and eventually go? And most importantly, is it relevant to you?

In this episode we speak to the Lead of Human Science at the Ineos Grenadiers Pro Cycling Team, Aitor Viribay, who has also worked with some of the biggest names in ultra trail running. He discusses how, when and why these very high carb intakes have become a thing in recent years, the scientific rationale behind it, when it’s used vs when it’s not, and whether non-professional athletes need to worry about these levels of intake.
