Fuelling is one of the most important factors in endurance performance. Many endurance athletes train well but underfuel during long sessions and races, which leads to fatigue, reduced performance and poor recovery. Carbohydrate is the primary fuel for moderate to high intensity endurance exercise. During long sessions, the body’s stored carbohydrate (glycogen) becomes depleted, and carbohydrate intake during exercise helps maintain energy levels and performance. Typical carb
