RaceFuel: Gel & Hydration Calc

Stop guessing your race nutrition. Hit your personal best without "hitting the wall."

RaceFuel is a carbohydrate, hydration and sodium calculator built for endurance athletes - runners, cyclists, and triathletes training for a 10K, half marathon, marathon, or triathlon. Whether you're planning a long training ride or race day fueling, RaceFuel takes the guesswork out of your nutrition strategy.

Simply enter your body weight, gender, sport, and session details, and RaceFuel generates a precise, easy-to-follow fueling plan tailored to you.

KEY FEATURES:

- Personalized Fueling Strategy: carbohydrate, fluid, and sodium targets based on your body weight, gender, sport type, and maximum hourly carb tolerance.

- Smart Session Parameters: adjust your plan by sport (running or cycling), duration, and intensity zone (Z1-Z5). Temperature is auto-fetched from real-time weather data for your location, so your hydration plan reflects actual race-day conditions.

- Gel Pantry: build your own stash of energy gels from popular brands (SIS, Maurten, GU, Precision Fuel & Hydration, High5, Clif, PowerBar, Enervit, Honey Stinger, Torq, Neversecond, 226ERS, Hammer, Spring Energy, and more), or add your own custom gels.

- Precise Minute-by-Minute Schedule: RaceFuel turns your plan into an exact timeline showing which gel to eat and when, based on what's actually in your pantry - not a generic guess.

- Caffeine Aware: track caffeine content per gel and get a smart caffeine dose reserved for the toughest part of long or high-intensity sessions.

- Live Session Mode: start your workout in-app and get local notifications reminding you exactly when to fuel, even in the background, with full pause and resume support.

- Save & Share Plans: save your fueling plans, revisit your history, and share a formatted plan with training partners or coaches.

- Beautiful Dark & Light Mode: a sleek, modern interface that's easy to read in any lighting, from pre-dawn training runs to bright race-day starts.

- Multi-language Support: available in English, Polish, German, Spanish, French, and Italian.

Whether you're a first-time marathoner, a seasoned triathlete, or a cyclist chasing a new PB, RaceFuel helps you plan your nutrition, stay hydrated, and race with confidence.
