Eat to Win
Runners often ask how much protein, carbohydrate, and fat they should eat each day. Because every runner is different, there isn't a simple answer. It all depends on your training volume, goals for losing or maintaining weight, and other factors. A good rule of thumb: Aim to get 55–65 percent of your total daily calories from carbs, 15–20 percent from protein, and 25–30 percent from fat.
