6 min read

According to sports dietitians, relying on whole, unprocessed foods can provide stable energy and a wider range of nutrients compared to highly processed sports products. This makes knowing what is the best real food to eat during a marathon a valuable skill for any runner looking to optimize performance and feel better on race day.

Quick Summary

This guide covers the top real food options for marathon fueling, including bananas, dried fruit, dates, and sweet potatoes, explaining their benefits for sustained energy and digestion. It offers practical advice on preparing and carrying these foods, compares real foods to gels, and provides tips to avoid common pitfalls like GI issues during the race.

Key Points

  • Practice with real food in training: Test all fueling strategies on long runs before race day to prevent digestive issues.

  • Choose easily digestible carbs: Focus on low-fiber, simple carbohydrates found in foods like bananas, dates, and sweet potatoes for sustained energy.

  • Replenish electrolytes: Real foods may not contain enough sodium. Add salt to savory foods or use an electrolyte drink to replace minerals lost in sweat.

  • Eat early and often: Start fueling after the first hour and take small, frequent bites (e.g., every 15-20 minutes) to maintain stable blood sugar.

  • Prepare your fuel for portability: Pre-package bite-sized portions in bags or pouches to make consumption easy while running.

  • Use a mix of food and gels if needed: It is not an all-or-nothing approach. Using real food for some fuel and gels for others can prevent palate fatigue and provide a quick boost when needed.

  • Avoid high-fat, high-fiber foods: These can slow digestion and cause discomfort. Save foods like nuts and high-fiber grains for before or after the race.

Why Choose Real Food for Your Marathon?

While energy gels and chews offer convenience, real foods present several advantages for endurance athletes. Whole food options are often richer in micronutrients, can lead to steadier energy levels, and might be easier on the stomach for runners who experience gastrointestinal (GI) distress from synthetic products. Eating real food can also provide a psychological boost by offering a change in taste and texture from the monotonous sweetness of gels, combating 'palate fatigue' on long runs.

The Science of Fueling with Whole Foods

Carbohydrates are your body's primary fuel during a marathon, and real foods are packed with them. Your body converts carbohydrates into glucose, storing it as glycogen in your muscles and liver. These glycogen stores can last for about 60-90 minutes of moderate-intensity running, but must be replenished during the race to prevent 'hitting the wall'. Real foods can provide both simple and complex carbohydrates, ensuring a steady release of energy. The key is choosing low-fiber, easily digestible options during the race to avoid stomach upset.

Top Real Food Options for Mid-Race Fuel

  • Bananas: This running staple is rich in potassium, which helps prevent muscle cramps, and provides easily digestible carbohydrates for a quick energy boost. Small pieces can be eaten regularly.
  • Dates: High in natural sugars and a concentrated source of carbohydrates, dates are a simple, portable energy source. Like other dried fruits, they pack a lot of carbs into a small package.
  • Dried Fruit: Raisins, apricots, and other dried fruits are excellent, low-volume carbohydrate sources. They are a great alternative to commercial products and have been shown to be just as effective in studies.
  • Mashed or Boiled Sweet Potatoes: A savory alternative to sweet options, sweet potatoes offer easily digestible carbs along with potassium and other vitamins. They can be mashed and stored in a pouch or eaten as boiled, salted chunks for a simple, savory snack.
  • Honey or Maple Syrup: Both are pure, simple carbohydrates that can be consumed directly from a stick or pouch. They provide a quick and natural energy hit.
  • Pretzels: Salted pretzels are an ideal option for replacing both carbohydrates and sodium lost through sweat. They also offer a crunchy texture that can be a welcome change.
  • Homemade Energy Bites: Creating your own energy balls or bites with ingredients like dates, oats, nuts, and nut butter allows you to control the ingredients and avoid additives.

Comparison: Real Food vs. Energy Gels

Feature Real Food Options Energy Gels
Carbohydrate Source Natural sugars from fruits, starches from potatoes, and honey. Formulated sugars like maltodextrin, glucose, and fructose.
Digestion Can be digested more slowly depending on fiber content, providing more stable energy. Must be low in fiber during race. Designed for rapid absorption, delivering a quick but sometimes jarring energy spike.
Nutrient Density Rich in vitamins, minerals, and antioxidants (e.g., potassium in bananas, vitamin A in sweet potatoes). Primary focus is on carbohydrates for fuel, with added electrolytes in some cases.
Cost Generally more cost-effective per gram of carbohydrate. Can be expensive, especially over the course of a long race or training cycle.
Preparation & Portability Requires some prep (mashing, cutting, bagging). Can be bulkier to carry. Conveniently packaged for easy, mess-free consumption while running.
Taste & Palate Fatigue Wide variety of tastes and textures. Less likely to cause palate fatigue. Limited variety of often overly sweet flavors, which can lead to taste fatigue.

How to Plan Your Real Food Marathon Fueling Strategy

  1. Test in Training: Never try a new fueling strategy on race day. Practice with your chosen real foods on long training runs to ensure your stomach tolerates them and you can consume them while running.
  2. Aim for Carbohydrate Targets: The standard recommendation is to consume 30-60 grams of carbohydrates per hour for runs over 60-90 minutes. Use your training runs to determine what amount works best for you. For example, a medium banana offers around 27 grams of carbs, and a small box of raisins is about 30 grams.
  3. Prioritize Low Fiber: In the 24-48 hours leading up to and during the race, minimize fiber intake to prevent GI distress. Stick to easily digestible, low-fiber options.
  4. Practice Hydration and Salt Intake: Real food options may contain fewer electrolytes than commercial products. Plan to replace sodium and other minerals lost in sweat by adding salt to savory foods (like potatoes) or using an electrolyte drink mix in your water.
  5. Focus on Small, Frequent Bites: Eating small portions frequently (e.g., every 15-20 minutes) is often easier to digest than consuming larger amounts less often. This keeps your energy levels steady and minimizes stomach upset.
  6. Pack Smarter: Carry pre-prepared, bite-sized portions in small resealable bags or reusable pouches. Some runners use a running vest or belt with dedicated pockets for carrying fuel.

Conclusion: Fuel Your Body the Real Way

Choosing real food to fuel your marathon is a viable and often superior alternative to traditional sports nutrition products. By focusing on easily digestible carbohydrates like bananas, dates, and sweet potatoes, and practicing your strategy during training, you can provide your body with sustained energy and a broader spectrum of nutrients. The right real food can not only power you to the finish line but also help you feel better throughout the race and aid in a quicker recovery.
