Your diet is an important tool in maintaining good health as well as a necessary element in promoting peak performance. Proper nutrition and hydration for runners can make or break a workout or race. The food you eat greatly affects how you feel, work, and think. A balanced diet for healthy runners should include these essentials: carbohydrates, protein, fats, vitamins, and minerals. Be sure you communicate your health goals and consult your primary care physician or a licensed nutritionist or dietitian when making changes to your diet.
