Keeping healthy sleep habits will help you give your all during each workout or race. Most teenagers and adults need between 8-9 hours of sleep per week. If you are a younger athlete (in middle or high school), try to get between eight and ten hours of sleep. Carbohydrates provide the body with energy and stamina during hard workouts. Protein stabilizes blood sugar and helps you stay full. Aim for a serving of each in every meal to give your body balanced nutrition.  Runners should aim to get sixty to sixty-five percent of their calories from carbohydrates. Pasta, bread, cereal, dairy, sports drinks, and fruits are all great sources of carbs.  Healthy food with a high protein content include: eggs, nuts, beans, tofu, and white meat. Some fat is important, but a runner's diet should be relatively low in fat. It should make up around twenty percent of your caloric intake and primarily come from monounsaturated fats (like avocados, olive oil, and nuts) instead of saturated fats (like whole milk, red meat, and butter). Drinking enough water can increase a runner's speed and stamina. How much water you should drink during a workout depends on the intensity and the environment you're exercising in. Keep an accessible supply of water or a sports drink with you while you exercise, and drink when you feel thirsty or notice signs of dehydration.  Try to drink at least 2–3 liters (0.53–0.79 US gal) (9-13 cups) of water per day.  Dehydration symptoms include: dizziness, dry mouth, excessive sweating, fatigue, extreme thirst, dark or strong smelling urine, or confusion. . It is important to stretch your muscles after you complete a run. Stretching will help to alleviate cramps and release tension in your muscles. Stretch your legs, especially your calves, to help prevent cramping.

Summary:
Get at least eight hours of sleep every night. Eat plenty of protein and carbohydrates. Avoid foods with a high fat content. Stay hydrated. Stretch after running
