HOW DO I MANAGE NUTRITION ON ULTRA-ENDURANCE RIDES?
Ultra-endurance cycling is as much about fueling as it is about pedaling. Without the right nutrition plan, fatigue, dehydration, and gastrointestinal distress can derail even the most trained athletes. Managing nutrition on ultra-endurance rides means balancing carbohydrates, proteins, fats, electrolytes, and hydration over long hours, while also adapting to environmental conditions and personal tolerance. This guide unpacks proven strategies—from pre-ride fueling to on-the-bike nutrition and post-ride recovery—to help cyclists perform at their best during rides that stretch into the double or even triple-digit hours.
Pre-ride fueling
Preparation for ultra-endurance events begins days before the ride, not the morning of. Carbohydrate loading, hydration strategies, and micronutrient balance are critical to building energy reserves that sustain long efforts. Pre-ride nutrition sets the stage for endurance, stamina, and mental clarity when the miles accumulate.
Carbohydrate loading principles
Cyclists should gradually increase carbohydrate intake 48–72 hours before the event, targeting 8–12 grams of carbs per kilogram of body weight daily. Complex carbs like rice, pasta, oats, and potatoes fill muscle glycogen stores. Avoid excessive fats and high-fiber foods that may cause gastrointestinal distress during the ride.

Hydration and electrolytes
Hydration begins before the starting line. Cyclists should drink steadily in the 24 hours leading up to the ride, consuming 500–700 ml of electrolyte solution the evening before. Sodium is especially important, as it helps retain fluid and prevents cramps. Caffeine can be used strategically the morning of the event, but excessive intake risks early dehydration.
A balanced pre-ride fueling routine ensures you roll out with topped glycogen stores, stable hydration, and confidence in your energy reserves.
On-the-bike nutrition
During ultra-endurance rides, consistent fueling is non-negotiable. The body burns through glycogen within hours, forcing reliance on external carbohydrate intake. Managing macronutrients, timing, and hydration while riding ensures sustainable power output and reduces risk of “bonking.”
Carbohydrate intake per hour
Current research supports consuming 60–90 grams of carbohydrates per hour for ultra-endurance performance. Blended carb sources (glucose + fructose) improve absorption and reduce gastrointestinal issues. Cyclists should mix solid foods, gels, and drinks to maintain energy variety and avoid flavor fatigue.

Protein and fat considerations
While carbs dominate, protein and fat play supportive roles during long events. Small protein doses (5–10 grams per hour) can reduce muscle breakdown, while moderate fats (nuts, nut butter, or avocado wraps) help provide steady energy during multi-hour stages. The key is balance—too much fat or protein slows digestion and risks stomach upset.
Hydration pacing
Cyclists should aim for 500–750 ml of fluids per hour, adjusted for heat and sweat rate. Sodium intake of 500–1000 mg per hour is recommended to replace electrolyte losses. Monitoring urine color and body weight fluctuations helps riders fine-tune hydration strategies on the fly.
The golden rule: never wait until you feel hungry or thirsty—fuel and drink proactively every 15–20 minutes to stay ahead of depletion.
Recovery after the ride
Post-ride nutrition is critical for rebuilding glycogen stores, repairing muscles, and restoring electrolyte balance. The recovery window—the first 30–60 minutes after finishing—is where nutrition delivers the most impact. For ultra-endurance cyclists, smart recovery ensures readiness for future rides and prevents long-term fatigue.
The 4:1 carb-to-protein ratio
Consuming carbohydrates and protein in a 4:1 ratio jumpstarts recovery. Options include recovery shakes, chocolate milk, or balanced meals with rice and lean meat. The goal is to replenish glycogen while supplying amino acids for muscle repair.
Carbs: rice, pasta, bread, fruits
Proteins: chicken, fish, eggs, whey shakes
Electrolytes: sodium, potassium, magnesium
Hydration reset
After hours of sweat loss, rehydration requires more than water. Electrolyte-rich fluids help restore balance and prevent post-exercise cramps. Weighing yourself before and after the ride can guide replacement—each kilogram of body weight lost equals roughly one liter of fluid deficit.
Long-term recovery foods
Beyond the recovery window, cyclists should focus on anti-inflammatory foods like berries, leafy greens, and omega-3-rich fish. These help reduce systemic stress and accelerate overall healing. Sleep, coupled with balanced nutrition, is the ultimate recovery enhancer.
Managing nutrition for ultra-endurance rides isn’t just about surviving the miles—it’s about thriving during them and bouncing back stronger afterward. With the right plan, riders can push limits while avoiding the pitfalls of poor fueling.
