Nutrition & Hydration Calculator for Riders
Fueling and hydration mistakes are one of the most common reasons riders struggle on long-distance brevets. This tool helps you plan ahead so you’re not guessing on ride day.
Use the calculator below to:
- Estimate your calorie and carb burn for a given distance, elevation, and pace
- Generate an hourly fueling plan. How many grams of carbs and how much fluid to take in per hour, adjusted for ride duration and temperature
- Calculate your electrolyte and sodium needs, especially important on hot or overnight rides
- Plan your drop-bags and carried food, splitting what you carry versus what you’ll pick up at controls
Enter your own numbers: weight, target distance, expected conditions and the tool will give you a personalized plan in seconds. These are general planning estimates, not medical advice, so test any strategy in training before relying on it during an event.
Calorie & Carb Burn Estimator
Estimates total energy expenditure and a baseline carb target for your ride, based on distance, elevation, weight and pace.
Fueling Plan Generator
Recommends carbohydrate and fluid intake per hour based on ride duration and temperature.
Electrolyte & Sodium Calculator
Estimates sodium losses and replacement targets - important for hot weather and overnight rides with heavy sweating.
Drop-Bag & Food Planning Tool
Splits your total calorie needs across carried food versus what you plan to resupply at controls.
These are general planning estimates, not medical or dietary advice. Test any nutrition strategy in training before relying on it during an event, and adjust to your own tolerance and any dietary or health needs.
