No more guessing race-day fuel.

FlutterDartRiverpodClean Architecture

RaceFuel takes weight, sport, duration and intensity, plus live weather data, and works out exactly how much carbohydrate, fluid and sodium a session needs. It then converts that target into a precise schedule of what to eat and when, built from the gels already sitting in the athlete's own pantry.

01Personalised Strategy
Carb, fluid and sodium targets calculated from weight, sport and intensity zone.
02Gel Pantry
A stocked inventory of gels from major brands, or custom entries, feeding every plan.
03Minute-by-Minute Schedule
Targets converted into an exact timeline of what to eat and when.
04Live Session Mode
Local reminders fire mid-session so the plan gets followed, not just written.
