UltraFuel: Ultramarathon Fuel

Fuel your race like you've got a pro crew.

Sponsored elites have their nutrition dialed in and a crew feeding them every few miles. Everyone else is guessing. UltraFuel closes that gap — a fueling plan built for your body, a gut trained to take it, and a crew that knows exactly what to hand you, and when.

UltraFuel learns from the training you already do and turns it into personalized carb, fluid, and sodium targets for race day. No population averages. No one-size-fits-all charts.

Plan — built from your runs, not a chart
- Syncs with Strava so your plan comes from your real training
- On Android, also import workouts through Health Connect (Garmin, COROS, and more)
- Turns your own runs into per-hour carb, fluid, and sodium ranges
- The more you log, the more personal your targets get

Train — a gut that's ready before the start line
- Stomach trouble ends more ultras than tired legs do
- UltraFuel folds gut training into your weeks of prep, building how much fuel your body can comfortably take on
- Note how each long run felt and your plan adapts week to week

Execute — a crew that knows the plan
- Share your race plan and your crew sees exactly what you need at every aid station: what to have ready, when, and how much
- A live race-day tracker keeps you and your crew on the same page
- Pair a crew member's phone in seconds with a QR code — no accounts to juggle

Built for places with no bars
- Logging, planning, and the live tracker all work with zero signal
- Your data syncs in the background when signal returns
- One login across phone and web — the same data everywhere
- A dead zone never costs your crew an entry

Getting started
UltraFuel is free during early access — training, gut coaching, race planning, offline crew tracking, and Strava sync are all included. Race Kit, a paid tier for race-day features, is coming after launch, and early athletes get founding pricing.

Built by an ultrarunner. No sponsorship, no crew required.

Every recommendation is grounded in published sports-nutrition research. UltraFuel provides informational fueling ranges to guide your own training and race planning — it is not medical advice and not a replacement for your doctor or dietitian.
