Fuelstate: Marathon Fueling
Race Nutrition & Gel Timing
Free · In‑App Purchases
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.

Fuel plan building got a major visual refresh.
Strategy now brings run setup, product selection, what-to-bring guidance, and pre-run prep into a cleaner, more connected flow. The fuel kit experience has been streamlined, saved setups are easier to manage, and the core planning surfaces now feel smoother, clearer, and more polished end to end.
This update also improves product-aware fueling plans, refreshes key Strategy details and transitions, refines the Pro and purchase experience, and includes reliability fixes across planning, paywall layout, and run preparation.
