Proper nutrition is critical for ultrarunners to sustain energy, support muscle recovery, and enhance performance during long-distance runs. Tailored nutrition strategies help in maximizing the potential of an ultrarunner’s physiology.
Macronutrients and Their Roles
Carbohydrates are the primary source of energy for ultrarunners, as they are converted into glucose, which fuels muscle activity and brain function. The recommended intake is 6-10 grams per kilogram of body weight. Proteins play a crucial role in repair and recovery of muscles, with an advised intake of 1.2-2.0 grams per kilogram of body weight daily. Fats are important for long-duration events, providing a dense energy source and supporting cellular functions. Ultrarunners should aim for a balance, incorporating high-quality sources of these macronutrients into their diets.
- Carbohydrates: Bread, pasta, rice, energy gels, bars
- Protein: Meat, eggs, dairy, legumes, protein bars
- Fats: Nuts, seeds, avocado, oils
Understanding Energy Sources
Throughout an ultramarathon, a runner’s body taps into different energy sources depending on intensity and duration. Initially, the body uses stored carbohydrates (glycogen), but as the race progresses, it increasingly relies on fats. Maintaining a consistent intake of calories from a mix of carbohydrates and fats helps prevent energy dips and maintains performance. Ultrarunners typically consume 200-300 calories per hour from a combination of solid foods like bars and more easily digestible forms such as gels.
The Science Behind Fueling Strategies
Fueling strategies during an ultra event are developed from scientific understanding of how the body utilizes nutrients over extended periods of exertion. Staying ahead of hunger and dehydration by consuming small, regular amounts of food and fluids can prevent the depletion of glycogen stores. Hydration with water and electrolytes is essential for nutrient transport and muscle function. Every ultrarunner may have a unique fueling strategy that works best for them, considering the duration of the event, the terrain, and individual metabolic responses.
- Hydration: Water, electrolyte drinks
- Fueling: Regular, small portions of food, and fluids
Hydration Fundamentals
Proper hydration is crucial for ultrarunners, as it involves maintaining fluid balance and electrolyte levels, which are both essential for peak performance. An understanding of electrolytes, sweat rate, and the impacts of dehydration is key.

Calculating Individual Sweat Rate
Calculating individual sweat rate involves measuring body weight before and after exercise, along with the volume of fluid consumed during the activity. This information allows runners to tailor their hydration strategy to their personal needs.
To calculate sweat rate:
- Weigh in pre-run (without clothes for accuracy)
- Run for a fixed time at race intensity
- Record amount of fluid consumed (if any)
- Weigh out post-run (without clothes)
- Subtract post-run weight from pre-run weight, convert to oz or mL
- Add to this number the volume of fluid consumed
- Divide by the number of hours run to find sweat rate per hour
Dehydration and Performance
Dehydration occurs when fluid losses exceed fluid intake, leading to a deficit in the body’s water balance. It can significantly impair an ultrarunner’s performance and can lead to:
- Increased heart rate
- Lower blood pressure
- Reduction in blood volume
- Increased core temperature
