Question: how many calories should a female runner eat?
Answer: For example, a 30-mile-per-week male runner needs about 20 to 22 calories per pound of body weight, or 3,200 calories per day for a 160-pound man. A woman running the same mileage needs only 18 to 20 calories per pound, or 2,400 calories a day for a 130-pound woman.
