Imposing mountain ranges, rustic valleys and the largest connected glaciated area in the Alps - This is a World Heritage of universal value. On the UNESCO Jungfrau-Aletsch Trail, participants in teams of 2 or 3 can discover the UNESCO World Heritage Swiss Alps Jungfrau-Aletsch.

With 250 kilometers as well as 18,000 meters of altitude, the E250 route is considered a tough test for all participants. We pass by Sefinafurgga, Hohtürli next to Blüemlisalphütte, Gasterental and Lötschepass, Suonenwege im Wallis, Blatten-Belalp, Aletschgletscher, Fieschergletscher, Goms, Grimselpass, Haslital and Rosenlaui. The competition takes place in partial autonomy which means that each athlete has the ability to manage between control posts, in terms of food, equipment, orientation and safety. The circumnavigation of the UNESCO World Heritage Swiss Alps Jungfrau-Aletsch is a huge challenge for the athletes and will therefore be run in teams of 2 or 3 for safety reasons (whole route).

On the course there are Life bases, where the athletes can get food and rest. In addition, there will be refreshment facilities along the course. As a participant you will feed yourself independently between the posts and must carry the mandatory gear as stated in the Race Regulations.


A very good physical condition and some experience in trail running are essential for tackling the E250. In addition, as a competitor you must be able to complete the race in a partial self-sufficiency according to the ethics of trail running. We reserve the rights to exclude persons from participating in the race. At the time of registration, each competitor must have a UTMB index entry in the 100K or 100M category or at least one 200K Ultra Trail completed since 1 January 2019 must be given as a reference. The organization reserves the right to check those references.

The UNESCO Jungfrau-Aletsch Trail will be completed in teams of 2 or 3 people.
