## What is Runtrition?

Plan your race nutrition with science-backed precision. Runtrition simulates glycogen depletion and tells you exactly when and what to eat during marathons, half marathons, ultras, and long training runs — so you never bonk.

Enter your race distance, target pace, and body weight. Runtrition calculates your carb burn rate and creates a personalized fueling schedule with precise timing for every gel, chew, or drink.
