Ultra Trail Grand Colombier - 16 km 2026

The 30 km Ultra Trail Grand Colombier begins in Seyssel, ascending 1,300 metres before concluding in Culoz, located at the base of Grand Colombier. This is the intermediate trail distance within a six-event series that shares the same finish location, offering routes from a 10 km trail up to a 120 km ultra. The longer races commence from various towns: Belley hosts the 120 km, Contrevoz the 80 km, Hauteville the 45 km, and Seyssel serves as the starting point for both the 30 km trail and the 16 km gravel run. The 120 km event allows for solo participation or a five-person relay, and the 80 km also provides a solo option or a three-person relay. Consequently, the event unites solo ultrarunners, relay teams, shorter-distance trail runners, and gravel runners at the single finish line in Culoz.
