One of the biggest changes in professional cycling in the last five years has centred on fuelling. Rewind to the Giro d'Italia in 2018, when Chris Froome went on an 80km solo raid over the Colle delle Finestre, his strategy of eating up to 100g of carbohydrates per hour was unusual and the secret to his success.
Look at this year, though, and those huge, solo attacks are no longer particularly uncommon, and pro riders will take in over 90g of carbs per hour in just training rides, more in racing.
