Carbohydrate Intake
Endurance athletes are super with their nutrition as it can become a limiting factor for performance. Carbohydrate (CHO), is the primary energy source for fueling moderate to high-intensity exercise, however, our CHO stores (i.e. glycogen) are small and therefore need constant replenishing. If we do not refuel our CHO stores, we risk 'hitting the wall', which can reduce performance significantly, or even stop you from finishing a race. In this video, we look at the scientific recommendations for CHO intake for endurance athletes to ensure we are consuming adequate amounts of CHO, so that we can train and perform better.
