Les Foulées de Decat' begins at Decathlon Mondeville in Calvados, near Caen, featuring a timed 10 km race as the main event. Held in June, it welcomes runners of all abilities and includes children's races. Some sources also mention a 7.5 km option, indicating a format more varied than a single start.
The course circles Mondeville, with the primary 10 km race characterized as a nature path rather than an urban circuit. Decathlon Mondeville organizes the event with a focus on sustainability: organic refreshments at the finish, waste management, reduced single-use plastics, and promotion of cycling or scooting, supported by dedicated parking. A race village and a group warm-up create a communal atmosphere before the run; one past event attracted 395 runners.
