Crest'zy Night begins after dark from the Mistral bridge in Crest, Drôme department, southeastern France. This race night is open to all, featuring a 1 km children's race, a 5 km run, and a 10 km trail race with approximately 100 m of elevation gain.
The route goes through the streets of Crest, along the Drôme river banks, and winds through the medieval lanes of the old town. A.S. ARMORIN organizes the event. A previous edition had 459 participants, positioning it as a local community night race rather than a large city event.
