Défi Vert - Les Toquées de la Dalle is an outdoor race series held in late April in Bordeaux, located in France's Gironde department. It is a Green Challenge, not a standard road race, offering a 13 km mountain-bike loop, a 5 km Bike and Run, and a 1h30 obstacle-course option.
The event spans seven parks, featuring running, VTT, obstacle racing, laser biathlon, canoeing, and climbing as part of the overall challenge. Situated in Nouvelle-Aquitaine near the Atlantic, the Bordeaux setting complements the event's playful tone, reflected in the phrase “Sûr que t as trop la dalle !” associated with its name.
