Cross Duathlon de Torcy is a short run-bike-run event at the Torcy leisure center in Torcy, France, organized by Triathlon Club Torcy. The main S-format race is a mixed open cross duathlon: 4 km of running, 11 km on a mountain bike, then another 2 km run. It is held early in the duathlon calendar and has been called by local clubs the first duathlon outing of the season.
The race attracts club athletes from the Paris region, including delegations from Sénart, and can serve as a first duathlon for newly licensed triathletes. Past accounts also mention repeat participants returning multiple times, including relay entries. The course is short enough for beginners, but the mountain-bike leg provides a different character than a road duathlon, with podiums still contended by club racers.
