Enduro Fuel

Stop guessing your race-day nutrition. Enduro Fuel turns your body stats and effort duration into a precise, science-backed fueling plan — carbohydrates, fluids, sodium, potassium, and protein, broken down per hour and for your entire effort. HOW IT WORKS Enter your weight, height, biological sex, and expected duration — from a quick 30-minute effort to a 12+ hour ultra — and get an instant, personalized plan. WHAT YOU GET • Carbohydrate targets per hour and total, with dual-transport (glucose + fructose) guidance for high-carb, long-duration efforts • Fluid targets based on estimated sweat rate, calibrated to avoid both dehydration and over-drinking • Sodium and potassium targets to help prevent cramping and hyponatremia • Protein targets for efforts over 2 hours, to reduce muscle breakdown • A ready-to-pack gear list — gels, water bottles, electrolyte tabs, and real food — scaled to your exact plan • Plain-language explanations of the sports science behind every number • Save unlimited plans to build a library of fueling strategies for different races and revisit anytime (one-time purchase, no subscription) BUILT ON REAL SPORTS SCIENCE Enduro Fuel's targets are grounded in published endurance nutrition research, including Jeukendrup's duration-based carbohydrate guidelines, ACSM/Sawka hydration standards, and ISSN protein recommendations for ultra-endurance athletes. WHO IT'S FOR Runners, cyclists, triathletes, hikers, and ultra-endurance athletes who want a fueling strategy dialed in before race day — not figured out mid-effort. Enduro Fuel works fully offline and doesn't require an account. Saving plans is available as a single one-time purchase — no subscription, ever. Enduro Fuel provides general planning estimates based on population averages and published research. It is not a substitute for personalized advice from a sports dietitian or medical professional. Individual sweat rates, gut tolerance, and conditions vary — always practice your fueling strategy in training before race day.
