Running Nutrition: Fuelling for a Marathon or Half Marathon

Preparing for and participating in a marathon or half marathon is about more than just running the miles – it’s about fuelling your body to perform at its best.

The food and drinks you consume before, during and after a run play a crucial role in powering your runs, preventing injuries and keeping you energised. Whether you are running for fun or gearing up for your next big race, what you eat before a run, during and after can significantly impact your performance.

Your body require a combination of hydration to maintain electrolytes, carbohydrates to fuel energy, protein to support muscle growth and recovery, and key vitamins to combat fatigue. Each element works together to prepare your body and maximise performance.

Here is your guide to everything you need to know about the food and drinks to help fuel your body before, during and after a marathon or half marathon.

What To Eat and Drink Before A Run?

The weeks leading up to a race are crucial for marathon and half marathon preparation. Your diet should include a healthy mix of carbohydrates, protein and healthy fats, along with staying hydrated. Building these habits early will ensure your body is well-prepared on race day. So, what are the best foods to eat before a run?

Pre-Run Nutrition Tips:

• Eat your pre-run meal 2-4 hours before a race to allow your body enough time to digest. This helps avoid discomfort during your run.
• Choose simple, easy-to-digest carbohydrates to provide quick energy. Great options include oats, bagels, fruit, peanut butter, yogurt, granola, and toast.
• Don’t forget protein – protein supports muscle recovery and helps prevent injuries. Stick to lean sources like chicken, fish, eggs, or plant-based options such as tofu and lentils.
• Drink water consistently and consider adding sports drinks with electrolytes to help maintain hydration and energy levels.

What To Eat and Drink During A Run?

When you are mid marathon or half marathon, providing your body with something that will quickly give you a boost of energy and keep you going till the finish line is important. It is all about providing easily digestible carbohydrates and maintaining hydration to prevent fatigue.

Mid-Run Nutrition Tips:

• Choose fast-digesting carbs like bananas, dates, honey, sweets, or energy gels. These will help replenish glycogen stores and keep your energy levels steady.
• Take advantage of water stations along the route to maintain hydration. Pay attention to factors like temperature, humidity, and distance, which affect how much fluid you need.
• Incorporate sports drinks to replace lost electrolytes and provide a steady energy boost, especially during longer runs.
• Practice your mid-run fuelling during training to find what works best for your body.

Energy Gels:

Energy gels are a marathon essential, as they provide a concentrated source of carbohydrates to replenish glycogen stores. Use them strategically during your run to prevent fatigue, particularly in the later miles.

What to Eat and Drink Post Run?

Post-run nutrition is just as important as pre- and mid-run fuelling. Eating the right foods after a race helps replenish energy stores, repair muscles, and aid recovery, ensuring your body bounces back stronger.

Post-Run Nutrition Tips:

• Pairing carbohydrates with protein can help with muscle repair and replenish glycogen levels.
• Re-hydrating lost fluids with water, sport drinks, or electrolyte drinks. Even consider drinks such as coconut water or chocolate milk for added nutrients.
• A protein drink after running is also a good alternative. Consider brands such as Myprotein, UFIT, Huel, Grenade etc.

Ideal Running Snacks:

• Bananas with peanut butter – A perfect mix of carbs and protein.
• Yoghurt with fruit – Combines quick carbs and muscle-repairing protein.
• Protein smoothies – Convenient and customisable.
• Eggs on toast – A simple and effective post-run meal.
• Nuts and seeds – Portable and protein packed.
• Hummus with vegetables – A nutritious and refreshing snack.

When to Eat After A Run:

Eating within 30 minutes of finishing your marathon or half marathon is recommended to maximise your recovery. During this time, your body is most receptive to absorbing nutrients, allowing you to recover faster and reduce the post-run soreness.

To conclude, prioritising your nutrition and hydration for a marathon or half marathon is essential whether you are training, taking part or just finished with a race. By focusing on what you eat and drink before, during, and after your runs, you’ll set yourself up for success. Experiment with different foods and drinks during your training to find what works best for your body and always listen to your body’s needs. With the right fuelling strategy, you’ll not only feel great but also achieve your running goals with confidence.
