Long rides go better when food, fluid, and sodium are planned before you roll out. This calculator estimates a practical range for carbs, bottles, and sodium based on ride duration, intensity, temperature, and rider weight.
Cycling Nutrition and Hydration Planner
Estimate carbs, fluid, and sodium for longer rides.
How to use this tool
Enter the planned ride time, choose the effort and weather, and add rider weight. Use the output to pack bottles, snacks, drink mix, and backup food before a long road, gravel, touring, or winter ride.
What the result means
Treat the numbers as a planning range, not a medical prescription. Heat, altitude, sweat rate, stomach tolerance, health conditions, and race intensity can change what you need.
