Trail SaintJeandaire begins and ends at Stade Jean Tardy in Saint-Jean-Bonnefonds, near Saint-Étienne. This timed outdoor trail race takes place in early March, offering two distances: 7 km and 17 km. Approximately half of each route follows unpaved paths, marking it as a local trail event rather than a road race in trail attire.
Runners set their own pace, but the race operates with a time limit and strict cutoffs. The 17 km race starts in the morning, with the 7 km following soon after. Both licensed and unlicensed runners are welcome. The longer race is open to juniors and older, while the shorter race is open to cadets and older. The event was previously known as Les Boucles Saint Jeandaires and is now held as Trail SaintJeandaire.
