Elian Allen · Answer 2

It is recommended to eat about 4 grams of carbs for every pound of body weight per day. So, it means that Cynthia (55 kg ~ 121 pounds) needs to take in about 500 grams of carbohydrates daily. Carbohydrates are important nutrient for marathon athletes to consume when preparing for a marathon because the skeletal muscles are fuelled mainly by glucose derived from carbohydrates. Glucose is stored in the form of glycogen to promote a decrease in fatigue during the race.
