Fuel for Victory: A Nutrition Guide for Long-Distance Races

We’ve all heard the joke: the only thing an endurance athlete thinks about while running is their next 4 or 5 meals. And, let’s be honest, it’s not far from the truth! Nutrition is often called the fourth discipline of endurance sports. No matter how hard you train, if you don’t fuel your body correctly, your performance will suffer. A well-thought-out eating plan can be the difference between crossing the finish line strong and “hitting the wall” 10k from the end.

To help you plan, we’ve created a simple guide on what you should do before, during, and after the race.

1. Before the Race: The Fueling Phase

Your sports nutrition strategy doesn’t start on race morning, but rather 3 to 4 days before the big day. The goal is to fill your muscles with glycogen (your main source of energy).

• Carb Loading: In the 3 days leading up to the race, increase your intake of complex carbohydrates. Think pasta, rice, potatoes, oats, and bread. This isn’t an excuse to eat pizza and sweets, but rather to make carbs the foundation of your meals. Keep fats and fiber in moderation to avoid discomfort.
• The Pre-Race Meal: On the night before, stick to a simple meal that you’ve already tested. Avoid unfamiliar foods or those high in fiber. A classic and safe option is a simple dish of white rice and grilled chicken.
• Race Morning: Have your breakfast 2 to 3 hours before the start. A bowl of oatmeal with honey and a banana, or a piece of toast with jelly, are ideal. It’s light and easy-to-digest fuel. And, the golden rule: never try anything new on race day!

2. During the Race: The Fueling Strategy in Motion

Maintaining energy levels is crucial to avoid fatigue and optimize your performance. The general rule is to replenish about 30-60 grams of carbs per hour, but this can vary per athlete.

• Your Best Friends: Energy gels and chews are your allies. They are easy to carry and consume, and they provide a quick burst of energy. Try to consume one every 30-45 minutes, always with water to help with absorption.
• Hydration and Electrolytes: Drink regularly and in small amounts. Plain water is good, but in longer races (over 90 minutes), you need electrolytes (sodium, potassium, magnesium) to replace minerals lost through sweat. Use a sports drink or salt tablets.
• Aid Station Tactics: Use the aid stations to hydrate and refuel. Don’t stop completely. Slow down, grab your cups, and walk while you drink to avoid losing your rhythm. Remember, practicing your nutrition strategy during your long training runs is the key to success.

3. After the Race: Muscle Recovery

The race doesn’t end at the finish line. What you do in the first few hours after finishing is vital for your muscle recovery and for avoiding soreness the next day.

• The Golden Window: Try to consume a combination of carbohydrates and protein within the first 30 to 60 minutes after crossing the finish line. A protein shake, Greek yogurt with granola, or a recovery bar are ideal. Protein will help repair muscle fibers, and carbs will replenish your energy stores.
• Rehydration: Continue to drink water and electrolyte beverages. Your body is dehydrated and needs to replenish fluids.
• Solid Meal: A few hours later, opt for a complete, balanced meal rich in protein and vegetables to continue your recovery.

Good nutrition will not only make you feel better during the race but also help you enjoy the experience more.

If you already have your nutrition strategy mapped out, it’s time to find the perfect race to put it into practice.
