About
TrailFuel turns race-day fueling from a guess into a plan you've trained for. Endurance athletes don't bonk because they picked the wrong gel — they bonk because their gut was never trained to absorb carbs at race intensity. TrailFuel fixes that. CALCULATE YOUR CARB NEEDS Enter any run — import a GPX file or set distance and elevation — and TrailFuel calculates exactly how many grams of carbohydrate per hour you need, plus your total for the run. Course intensity, duration, and your own tolerance all factor in. TRAIN YOUR GUT, PROGRESSIVELY Log what you actually ate and how your stomach felt after each run. TrailFuel builds a personal GI-tolerance profile and nudges your carb target up one safe step at a time — so race day is never the first time your gut sees 80g/hr. BUILT TO PREVENT GI DISTRESS GI distress is the #1 sourced cause of ultra DNFs. TrailFuel is designed around your stomach, not just a generic carbs-per-hour number. WHO IT'S FOR Trail runners, marathoners, ultra-runners, cyclists, and triathletes who train for months and refuse to let fueling be the weak link. SUBSCRIPTION TrailFuel is a subscription with a 1-week free trial on the yearly plan. Monthly and yearly options available. Cancel anytime in your App Store settings.
