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. When registering, each team member must provide at least 1 completed Ultra Trail participations (at least 100 km each) as a reference and possess an UTMB Index in the 100M or 100K category.

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