Run on these epic ridgelines with panoramic views of the crystal-clear lakes and the towering peaks of the Eiger, Mönch & Jungfrau. These are more than a race; each race will be an unforgettable journey through one of the most awe-inspiring landscapes on Earth.

Both the 27k & Up and Down routes are unique challenges taking runners over the Aare River that joins Lake Thun to Lake Brienz then up vertically into the terrain around the Harderkulm, a stunning viewpoint offering breathtaking panoramic views of the surrounding landscapes, including the Eiger, Mönch, and Jungfrau mountains, as well as both Lakes.  The running is technical and engaged with some faster sections on the descents.  The 50K route sees the 27K extend into the gorgeous rolling valley of the Beatenberg area, where you’ll run alongside Lake Thun and through mountainous River gorges.
