You should aim to eat a healthy, balanced diet whatever your activity level, as this will provide you with all the nutrients you need. Starchy and other forms of carbohydrate provide a source of energy for your body to perform at its best, no matter what your sport or activity.In general, the more you exercise, the more carbohydrate you need to include in your daily meals and around exercise. A demanding exercise regime will use up your stored energy from carbohydrate quickly. ~ Berceste
