Six jobs, one fueling plan
A race fueling plan has to get six separate things right. Here is how CarbRate handles each one, with the research behind it and the screens that do the work.
Built for your exact course
CarbRate places every gel and drink on your race’s real elevation profile and its published aid stations, so each feed lands on a runnable grade with water in reach.

Personalized to your body and goal
CarbRate builds your fueling plan from your weight, goal time, measured sweat rate, gut tolerance and race-day weather. Twelve questions, and every number is labelled measured or estimated.
