Flat Equivalent Calculator

Compare a mountain route to a flat one using a GPX profile and energy cost model.

A 100 km mountain race with 6000 m of elevation gain is not just 100 km. Your legs, lungs, and race clock will tell you it felt like much more. This tool calculates that real effort: how many flat kilometers your mountain route actually equals. Use the result to set realistic pacing, compare routes, and plan training volume that matches what race day will demand.
