The Walser Ultra Trail begins and ends at Hirschegg Dorfplatz in Vorarlberg, Austria. Runners start early in the morning in late July. This is the longest ultra distance within the Walser Trail Challenge, covering 63 kilometers on alpine trails with 3,900 meters of elevation gain.
The organizer describes the event as the Walser "U," an alpine challenge for trail runners. The course profile indicates a mountain-focused day rather than a flat, fast race. The distance is substantial, and the significant elevation gain emphasizes climbing and descending. Registration has a cap, and on-site entries may close once the limit is met. The event provides both rules and a liability document for participants.
