Q. I am training for my third marathon and need to pay close attention to my nutrition, but I am confused about the calorie intake needed to maintain a healthy weight during training. How can I figure out how many calories I should be eating during my training?
Answer. Running burns a lot of calories. Running 10 or 20 miles at a time really burns a lot of calories. Unless you increase your calorie intake to compensate, you’ll probably start losing weight.
