90 g of carbohydrates per hour: who is it for, when and in what form?

For endurance efforts of 2h30 and over, the publication recommends up to 90 g of carbohydrates per hour, by combining sources that use multiple absorption pathways, typically glucose or maltodextrin with fructose.

More is not automatically better

This target mainly concerns trained athletes and long events. It assumes a strategy tested in training: suddenly increasing intake on race day can lead to digestive issues.

A protocol to be tailored

Duration, intensity, digestive tolerance and the availability of fuelling opportunities should determine the amount. For personalised medical or nutrition advice, it remains necessary to consult a qualified professional.
