Aletsch Halbmarathon

The Aletsch Halbmarathon is a mountain running event located within a UNESCO World Heritage site. The main race covers a distance of 21.1 km and features an elevation profile that provides views of the Great Aletsch Glacier and the surrounding four-thousand-meter peaks of the Valais Alps. The event attracts over 2,700 participants annually from domestic and international locations.

In addition to the main half marathon, the event includes different formats held over two days:

  • 21.1 km (Aletsch Halbmarathon)
  • Mini-run (Aletsch Samstagsrennen)

The event is part of the UNESCO World Heritage Trophy. The organizers provide various services for participants and spectators, including a lost and found office, accommodation information, and travel recommendations. Important infrastructure such as start and finish areas are clearly defined, and spectator hotspots are designated for those following the race. Registration typically opens several months in advance in early November. Visit the organization's website for the most recent information.
