Everything OnCourse Fueling does

A race-day fueling plan from your route — smart, readable, free.

Plan

Time, not just distanceThe route becomes a time line from a cycling power model — climbs stretch the clock, descents compress it.
Smart auto-fillPlaces carbs to hit your g/h target, pulls intake before climbs, keeps it off descents, and tells you why.
Plan vs. targetLive carbs / fluid / sodium per hour with heat factored in, plus coach checks and warnings.
Basic & AdvancedBasic to sketch & print fast; Advanced for per-item nutrition, temperature and a rider model.
