Le Super Trail Nantais begins and ends at Stade de Procé in Nantes. Runners depart in the morning for a trail race on the city’s western side. Les Foulées Nantaises, the organizers of Les Foulées du Tram, host this event, which features two distances: the 18 km Chezin'Nature and the 10 km Chezin'Run.
The 18 km course departs the stadium, proceeds towards Saint-Herblain via the Val de Chézine, and then returns to Nantes through Parc de Procé before concluding on the stadium track. This race is a straightforward, community-focused event, not a large spectacle. Club runners receive a small discount on entry, and all finishers are required to return their bib and timing chip at the finish line.
