Fuelstate: Marathon Fueling

Build a race-day fuel plan from the gels, drinks, and electrolytes you already own. Get what to bring, gel timing, live countdowns, and post-run gut feedback.

Turn the gels, drink mix, electrolytes, and caffeine you already use into a personalized fuel plan for race day. Fuelstate shows what to bring, when to take it, and how to follow the plan live during your run.

Built for marathon, half marathon, ultra, triathlon, and long-run training, Fuelstate helps runners plan carbs, sodium, fluid, caffeine, gel timing, and race-week carb loading without guessing.
