Runner’s Diet – Principles, Meal Plan, Supplementation
Running is one of the most popular sports worldwide - some prefer recreational jogging, others interval training, and many focus on long-distance running. What many runners don’t realize is that daily nutrition can significantly impact endurance and athletic performance. What should a runner’s diet look like? What should you eat before a run, and what foods are best after training? How do you plan a balanced meal plan for runners?

Runner’s diet - basic rules
Short-distance runs are a favorite among many athletes, but long-distance running is also growing in popularity, often practiced recreationally. For many, running is a way to test their limits, step out of their comfort zone, and enjoy active relaxation.
Regardless of distance or frequency, runners need more than training alone – nutrition plays a crucial role. Regular, intense activity increases energy demands and requires a higher intake of essential macro- and micronutrients.
Since running is an endurance sport, the body needs a steady supply of energy to sustain prolonged effort. Carbohydrates are the main energy source, and research suggests they should make up 60–70% of a runner’s daily calorie intake. At the same time, a proper diet should include high-quality protein and healthy fats, as well as vitamins, minerals, and adequate hydration.
It’s important to note that a runner’s diet should always be tailored individually – depending on training frequency, duration, goals, and intensity. The diet of a long-distance runner may look very different from that of someone running primarily for weight loss.
Runner’s diet - calorie needs
Regular endurance training increases calorie requirements, especially for long-distance runners who exercise for hours at a time. Energy needs depend on several factors, including:
- age
- gender
- physical condition
- fitness level
- body composition
- training intensity
- training goals
A general estimate can be calculated using the Harris-Benedict equation to determine basal metabolic rate (BMR), then multiplying it by the appropriate physical activity level (PAL). For precise calculations, it is best to consult a sports nutritionist.
Running on an empty stomach - is it a good idea?
Many athletes run early in the morning before breakfast, believing that fasted training promotes fat burning. While eating beforehand isn’t strictly required, running without food is not recommended for those prone to hypoglycemia. Some studies suggest that fasted running increases the risk of injury, muscle loss, and lowered immunity. For most people, a light snack before training is a safer option.
Runner’s meal plan - what to eat before training?
A pre-run meal should be light, easy to digest, and high in carbohydrates to provide energy. About 2–3 hours before training, complex carbs are recommended since they digest slowly, keeping you full and releasing energy steadily. Good options include brown rice risotto with vegetables and chicken breast or oatmeal with nut butter and fruit.
About an hour before running, a small snack rich in simple carbs with a high glycemic index is ideal. These digest quickly, giving the body fast energy without causing digestive discomfort. Options include an energy bar, dried fruit, semolina porridge with fruit, rice cakes, or a white bread sandwich.
Before races, only familiar foods should be eaten to avoid digestive issues and ensure optimal comfort.
For long-distance events, mid-run fuel may also be necessary – sports gels and energy bars are commonly used.
Runner’s meal plan - what to eat after training?
The post-run meal is just as important as the pre-run one. It should include protein to support muscle repair and carbohydrates to replenish glycogen stores. Studies suggest eating within two hours after finishing exercise.
Examples include a whole grain tortilla with cottage cheese and vegetables, pasta with chicken, spinach, and sun-dried tomatoes, or yogurt with oats.
Runner’s diet - what to eat on rest days?
Nutrition matters not only on training days but also during recovery. While calorie needs may be slightly lower on rest days, meals should still be balanced and nutrient-rich.
A proper rest-day diet should include plenty of fruits and vegetables, lean protein, complex carbs, and healthy fats. Hydration is equally important for recovery.
Why is a balanced runner’s diet so important?
A well-balanced diet provides the energy needed for training and helps support muscle function, strengthen immunity, reduce the risk of muscle loss, and improve performance.
It can also promote fat burning, reduce the risk of injuries, and aid in recovery after workouts.
Supplements for runners
For recreational runners with low-to-moderate training intensity, food alone usually meets nutritional needs. However, long-distance and competitive runners may benefit from supplements to support performance and recovery. Commonly recommended options include:
- carbohydrate supplements – especially useful during endurance runs over 60 minutes, when 30 g of carbs per hour is advised;
- caffeine, which taken before exercise may improve endurance and delay fatigue;
- beta-alanine, which may enhance muscular endurance;
- protein powders, which help muscle recovery and reduce catabolism.
Runners may also use supplements that support joint and bone health, such as MSM or glucosamine, as well as multivitamins and mineral complexes to cover any deficiencies.
