48 Stundenlauf Brugg 2026

The 48 Stundenlauf Brugg is an ultrarunning event held on the Aareinsel in Brugg, Switzerland. Races are measured by time, not fixed distance. Participants can choose 6, 12, 24, or 48-hour races, run solo or in teams. A sponsored run for Pro Infirmis is also part of the program, allowing participants to complete laps for charity. The event takes place on an October weekend and is open to spectators. The course is a circuit at Geissenschachen, meaning the race involves repeated laps on the island rather than a point-to-point route. Swiss Ultra Running sanctions the Swiss Championships for the 6, 24, and 48-hour distances at this event, which has also hosted 12-hour championship races. Food, music, and lighting are provided, essential for races extending through the night. Recent winning distances for the 48-hour race have exceeded 300 km, indicating a competitive field. However, the format accommodates teams, charity runners, and those wishing to participate in the weekend's activities.
