Col de Porte - Le Mauchon

Follow this path as far as the locality of Les Frettes. From there you can take the there-and-back singletrack variant which ends with a few rocks to "climb" up to the summit. You'll then descend to the riverbed and then go back up to Gervais before returning to the Col de Porte pass via Le Mauchon.

The calculation of the difficulty of each course takes into account the length, the positive vertical drop, the greatest continuous positive or negative vertical drop as well as the technicality of the terrain.
