Trail des 3 Villages is a short trail race in Villieu-Loyes-Mollon, located in the Ain department of eastern France. The primary race covers approximately 13 km with about 163 meters of elevation gain and loss, positioning it between a quick local race and a more challenging mountain trail.
The course winds through fields and woods, runs alongside sections of the Ain river, and crests at 294 meters. The event offers a hiking option and children's races, contributing to a community race-day atmosphere rather than a specialized running event. The course is rated medium difficulty and is not permanently marked, so participants should rely on event-day markers instead of a trail available for use year-round.
