Madrisa Trail Klosters presented by LOWA

The Madrisa Trail Klosters presented by LOWA is a two-day alpine trail running event held in the mountain landscape of Klosters‑Madrisa, Switzerland. The event weekend (14–15 August 2026) brings together multiple race distances under a single festival-style programme, with the flagship T54 Trail standing out as a high‑alpine ultra. The organiser presents routes that emphasise technical singletrack, panoramic high‑mountain views and sustained elevation, aiming to offer an authentic mountain running experience for a broad range of participants.

The T54 (54 km / +4,020 m) is described as a challenging ultratrail with extensive trail content and pronounced elevation, while shorter options and a kids' run provide entry points for less experienced runners and families. The official site provides practical pages (rules, AGB, privacy), registration via Datasport, and links for results and photos; mandatory equipment lists and a detailed starter package are published for the longer distance. Participants are advised to consult the organiser's pages for the latest route, mandatory kit and logistical details before registering or travelling.
