ToussOTrail is a new nature race in Toussieu, organized by the local Toussieu Team Trail association. Its first edition offers two trail-running routes, 12 km and 25 km, plus a 10 km hike and children's races, catering to runners, walkers, families, and volunteers.
The trails are described as playful rather than just fast, featuring short sharp climbs and singletrack sections along the Ozon river. The event maintains a local, friendly atmosphere, with trail running, hiking, children's events, and general entertainment sharing the same program.
