What does Kilometer-Effort (km-effort) mean ?

The 4 race categories are based on the km-effort, a globally recognized formula for measuring the race distance in trail running by considering both the distance and elevation gain to calculate the perceived distance.

The km-effort is calculated by adding 1km to the race distance for every 100m of elevation gain.

For example, a race of 50km and 2,500m of elevation gain has 75 km-effort.
