Venez Décrocher la Dune takes place in Annoville, Manche department, Normandy, with races set between the harbors of Regnéville and Vanlée. It is a coastal trail event featuring sand, dunes, beach sections, and seaside paths, offering an 18 km trail, a shorter approximately 10 km route, children’s options, and a color-run format.
The courses utilize the west Normandy shoreline instead of a road-race layout, meaning runners navigate soft sand, open beach, and dune paths near the water. The event has also used the coast around Tourneville-sur-Mer. By its fifth edition, organizers had revised the routes, added a marathon, and included a hike alongside the trail races.
