Nancy Riv Action is an untimed obstacle race in Nancy, France, in the Grand Est region. The listing does not give a regular month, so the useful basics are the format: a 6 km family route and an 8 km obstacle route with 20 obstacles. Costumes are encouraged, which gives the event more of a fun-run feel than a strict race-against-the-clock setup.
The shorter course is aimed at families and groups who want to do the event together, while the longer course is built around obstacles that test strength, determination, and teamwork. The field is not limited to serious obstacle racers; the event also invites people running for fun, and the main draw is getting through the challenges rather than chasing a finish time.
