Randonnée de cloture du CODEP 40 is a cycling event held in October, based in Mont-de-Marsan, Landes, southwest France. It functions as a club-style randonnée, not a formal race, offering routes for both mountain-bike and road cyclists. The shorter VTT routes are 23 km and 31 km, both starting at 09:00. Road cyclists can select a 45 km route, and a longer 75 km option is designated as a cyclosportive-style ride.
The event is associated with CODEP 40, the Landes departmental cycling committee, and its name indicates a season-ending ride rather than a distinct competition. The event's structure appears practical and community-focused, featuring multiple distances and modest entry fees, with some free categories. Participants can choose a brief off-road route in the morning or a longer road ride, both originating from Mont-de-Marsan.
