Nice section of about a kilometer. Very popular with mountain bikers, it is very interesting for trail running. On rainy days this segment can get very muddy. So choose your trail shoes adapted to face the terrain with safety. Going uphill, this is an opportunity to test yourself on steep slopes that are fairly frequent in trail running.

Surprising single which evolves in the middle of the forest on a mound of earth with some technical passages. The path is sometimes steep. It is easier to take in the direction Coye la forêt towards Luzarches. In the other direction, there are about fifteen very steep meters, impossible to get on the saddle.
