1 km long and average gradient 9.4%, steepest 100m 14.9% ends at the top on an unpaved road, so those who want to cycle further are better off with gravel or VTT.

Here we find the start of the Mille monts trail, a loop of 27 kilometers and approximately 600 meters of elevation gain, in Pas-de Calais. The route is very pleasant, slightly hilly, perfect for enjoying mountain biking.
