Training for a half marathon is a rewarding challenge that requires more than just logging miles. Your nutrition plays a crucial role in fueling your body for those long runs, aiding recovery, and enhancing overall performance. As we approach half marathon season, this will guide you through the essentials of half marathon nutrition and provide a detailed 16-week nutrition plan to support your training journey.

The Basics of Half Marathon Nutrition

1. Carbohydrates: Your Primary Fuel Source Carbohydrates are the primary energy source for endurance activities. They are stored in the muscles and liver as glycogen, which your body uses during exercise. Aim to include complex carbohydrates such as whole grains, fruits, and vegetables in your diet.

2. Protein: The Building Block for Recovery Protein is essential for muscle repair and recovery. Incorporate lean proteins like chicken, fish, beans, and dairy products into your meals. Protein helps to repair the micro-tears in muscles that occur during training.

3. Fats: Essential for Energy and Health Healthy fats provide a concentrated energy source and support overall health. Include sources like avocados, nuts, seeds, and olive oil. Avoid trans fats and limit saturated fats.

4. Hydration: Stay Ahead of Thirst Proper hydration is vital for performance and recovery. Aim for at least 8-10 cups of water per day, and increase your intake on long run days. Consider adding electrolyte drinks to your routine to replace lost minerals during intense workouts.

5. Timing: Fueling Around Workouts Eating the right foods at the right times can enhance your training. Aim for a balanced meal 2-3 hours before your runs and a carb-rich snack about 30-60 minutes before. Post-run, focus on replenishing glycogen stores and repairing muscles with a snack or meal containing both carbohydrates and protein.
