Madrisa Trail Klosters

Madrisa Trail Klosters is a multi-distance trail running event in the Swiss Alps presented by LOWA. Held 14–15 August 2026, it brings together five races from a short introductory T11 to the flagship T54 ultratrail. The event hub is Bahnhofplatz Klosters and the courses run on alpine singletrails with technical sections and wide panoramic views, emphasising authentic mountain trail running. The weekend combines competitive racing with a festival atmosphere for participants and spectators.

The T54 (54 km, 4,020 m ascent) is promoted as the most demanding route, while the T33, T24 and T11 provide progressively shorter alpine challenges suitable for experienced runners and newcomers. The published programme lists registration and bib-collection windows, mandatory equipment checks for longer distances, an expo and food services, and dedicated prize-giving times. Organised by Verein Runningsports.ch, the event also includes a Kids Run and a race village atmosphere on Bahnhofplatz for families and supporters.
