February 23, 2025,Boucle Étang de Saulx-les-Chartreux – Viaduc des Fauvettes au départ de Palaiseau - Villebon

Be careful in the Janvry area in the forest, the route is almost impassable due to the mud and large pools of water. The wet winter, combined with the passage of quads and motocross has destroyed the trails.
