Nutrition plays a vital role in your performance as a long-distance runner, impacting your energy levels, recovery, and overall health. In this guide you will learn from our experts how to build a strong diet for your long runs.

How to create a strong diet

To support your training, focus on building a well-rounded diet that includes a variety of whole foods, including: 

  • ​​Carbohydrates: Your primary energy source.
  • Proteins: Essential for muscle repair and recovery.
  • Healthy Fats: Provide sustained energy and support overall health.
  • Vitamins and Minerals: Help maintain bodily functions and prevent fatigue.

Importance of carbohydrates and what types to eat

Carbohydrates are especially crucial for endurance runners, as they provide the glycogen stores your body relies on for sustained energy during long runs. Without adequate carbohydrate intake, you risk running out of fuel mid-race, which can significantly hinder your performance.

Focus on consuming complex carbohydrates such as whole grains: 

  • Oats: Great for breakfast as oatmeal or overnight oats.
  • Quinoa: A versatile grain that can be used in salads, as a side dish, or in soups.
  • Brown Rice: A staple for many meals, providing sustained energy.
  • Whole Wheat Bread and Pasta: Ideal for sandwiches or as part of a pre-run meal.
  • Barley: Perfect in soups or stews.

Fruits: 

  • Grapes: Quick energy and hydration in a convenient bite-sized form.
  • Bananas: High in potassium and easy to digest, making them a popular pre-run snack.
  • Berries (Blueberries, Strawberries, Raspberries): Rich in antioxidants and great for recovery.
  • Oranges and Clementines: Provide vitamin C and hydration.

And vegetables:

  • Sweet Potatoes: Rich in beta-carotene and perfect for a pre-run meal.
  • Beets: Known for boosting endurance, they can be roasted, juiced, or added to salads.
  • Peas: A good source of carbs and protein.

These foods not only provide lasting energy but also deliver fiber, vitamins, and minerals to support overall health.

Incorporate carbohydrates into every meal and consider “carb-loading” in the days leading up to your race. This strategy involves increasing your carbohydrate intake slightly to ensure your glycogen stores are fully stocked for race day.

Importance of protein and where to get it

Protein is another essential macronutrient that aids in muscle repair and recovery, especially after intense training sessions. Consuming protein after your runs can help rebuild muscle fibers, minimize soreness, and reduce the risk of injury.

Good sources of protein include lean meats like chicken and turkey, fish such as salmon and tuna, eggs, dairy products, beans, lentils, tofu, and nuts. If you’re on the go, consider protein shakes or bars as convenient options to meet your needs.

Include health fats

Healthy fats are often overlooked but are essential for long-distance runners. They provide a slow-burning energy source and support overall health, including brain function and hormone regulation. Some good choices include: 

  • Avocados
  • Nuts
  • Seeds
  • Olive oil
  • Fatty fish like salmon

Incorporate these into your meals to maintain balanced energy levels throughout your training.

Keep your body properly hydrated

Hydration is just as important as food when it comes to running performance. Dehydration can lead to fatigue, cramps, and decreased endurance, so it’s vital to drink enough fluids throughout the day.

During training and races, aim to drink water or electrolyte-enhanced beverages to replace the fluids and salts lost through sweat. Monitor your urine color—it should be pale yellow—as a quick indicator of hydration status.

As you approach race day, developing a nutrition strategy becomes increasingly important. Practice your fueling plan during long runs to determine what works best for you, including the timing and types of snacks or gels you may want to consume. Many runners find that consuming carbohydrates during the race helps maintain energy levels, especially for longer distances like half-marathons. Pay attention to your body’s signals, and be mindful of how different foods affect your performance, ensuring that you feel at your best when it matters most.
