Carbohydrate Recommendations for Marathon Runners

ultra-endurance runner followed general guidelines for a single bout endurance event which are 10 grams carbohydrates/kg body mass/day and 1.2-1.6grams protein/kg body mass/day. The conclusion was that he had adequate levels of carbohydrates and protein to provide the daily energy needed and no loss of body mass was indicated. One additional study
