13 km thiernois 2026

The 13 km Thiernois is a hilly running event in Thiers, France, centered on a 13 km main race through the upper town. It combines trail running effort with city running: participants navigate climbs, descents, stairs, and narrow old alleys instead of a flat road course. A 5 km option offers runners and walkers a shorter participation choice. The course crosses several areas of Thiers, featuring heritage sites within the town and vistas toward the Livradois mountains. The participant field is predominantly local and mass-participation focused, rather than elite-only, with the shorter distance intended for those seeking a more accessible format. Near the start and finish, organizers include activities, making the day feel like a community race as well as a challenging 13 km run.
