KM 0 — THE START

Fuel every climb,
not every kilometre.

Ultra Planner computes your fluid, carbs, and sodium per segment — weighted by time on feet, not flat distance — so a steep 5 km and a runnable 5 km never get the same plan.

How it works

  1. 01

    Enter your race

    Distance, elevation gain and loss, start time, and your goal finish. Import a GPX and the route fills it in for you.

  2. 02

    Add your aid stations

    Cumulative distance and elevation for each stop — plus drop bags, crew access, food, and rest time.

  3. 03

    Get your plan

    A segment-by-segment table: per-leg fluid, carbs, sodium, arrival clock times, and the exact gear to carry.
