Eating anything you want may lead to weight gain after a few months of regular running. Instead, focus on a healthy balanced diet.
- Eat something light that is high in carbohydrates 2 hours before you start running.
- If you're going to run longer than 90 minutes, consume 100 calories after an hour and another 100 calories every 45 minutes.
- After a long run, eat some carbs and protein within 30 minutes. The ratio of carbs to protein is 3 to 1.
