Race Day Fuel for the Waterford Viking Marathon
For 2016, Waterford Viking Marathon has teamed up with the Department of Health, Sport & Exercise Science in the Waterford Institute of Technology to provide expert training information in the run up to the event. This week, performance physiologist Bruce Wardrop examines some recent research which will help you plan your race day nutrition strategy.
Have you considered what you are going to eat to get you through 2016 Waterford Viking Marathon? With only weeks left until the start of the race, now is the time to start planning & practicing your fuel strategy for the race itself. Depending on your weight, completing the 42km course will require anywhere from 2500 to >3500kcal. To meet this demand, your body will burn a mix of carbohydrate and fat. At rest, this mix is typically 30-40% carbohydrate and 60-70% fat. During low intensity exercise this shifts to roughly 50% carbohydrate and fat, with marathon runners burning about 60-80% carbohydrate and 20-40% fat. Well-conditioned athletes are better able to utilise fat and are less reliant on carbohydrate.
