Lore & Trivia
The Eiger Ultra Trail runs beneath the most infamous mountain face in the Alps — the 1,800m Eiger North Face (Nordwand) that killed dozens of climbers during the golden age of alpinism and earned the nickname Mordwand ("murder wall"). The 101km course with 6,700m of gain circles the Eiger, Mönch, and Jungfrau through the Bernese Oberland, crossing alpine passes with views that routinely stop runners in their tracks. The Jungfrau region is Swiss tourism at its most dramatic, and the race takes full advantage: mountain railways, alpine villages, cow bells, and the ever-present North Face looming overhead.
- ▸ 101km with 6,700m of gain circling the Eiger, Mönch, and Jungfrau.
- ▸ The Eiger North Face is one of the deadliest mountain faces in the Alps.
- ▸ Bernese Oberland setting — classic Swiss alpine scenery.
