La Vendéenne begins and ends in St-Mars-la-Réorthe, a village in France's Vendée department. It is a cyclosportive, meaning participants select a marked road course and complete it as a group challenge, not a closed professional competition. The event takes place in spring and offers three distances: 50 km, 85 km, and 135 km.
The courses traverse the Vendée bocage, with undulating countryside with narrow lanes, hedgerows, and steep, short ascents. The local climbs present the primary challenge, with gradients exceeding 15% on some sections, ensuring even the shortest route demands effort. Vélo Club Les Herbiers organizes the ride. The available distances accommodate newer cyclists while providing a substantial challenge for experienced riders. The event's successful first running led to its continuation, and post-event photo collections are featured in its online presence.
