Question: how many grams of carbs should i eat before a run?
Answer: To get into the specifics, aim for a carb intake close to 3.6 to 5.5 grams per pound of body weight in those one to two days immediately before the race. When you do the math, this tends to be a whole lotta carb, and the reason why protein and fat often get put on the back burner in the hours before the race.
