A legendary Alpine marathon starting in Interlaken and ascending through stunning Swiss scenery to Jungfraujoch (Top of Europe) at 3,454m before descending to the finish in Grindelwald. The race features dramatic elevation changes with panoramic views of the Eiger, Mönch, and Jungfrau peaks throughout.
Cool alpine conditions with variable weather. September offers relatively stable conditions but mountain weather can change rapidly. Expect cooler temperatures at higher elevations with possible afternoon thunderstorms.
The Race
Interlaken
The Jungfrau Marathon was founded in 1999, during the golden age of mass-participation running. Now 27 years old, it has established itself as a beloved fixture in Interlaken, growing from its early editions into a race with genuine character and loyal following.
The fastest time ever recorded at the Jungfrau Marathon is 03:16:00, set by Simon Strache in 2018. Every year, new contenders line up hoping to challenge that mark on the streets of Interlaken.
With 2520m of elevation gain, the Jungfrau Marathon is not a course for the faint-hearted. The climbs are where races are won and lost — where the gap between training and undertrained reveals itself without mercy. Locals say the course doesn't beat you; it just waits for you to beat yourself.
The Jungfrau Marathon carries an "extreme" difficulty rating for good reason. The combination of terrain, conditions, and distance creates an event where finishing is a genuine achievement. Drop-out rates are high, preparation requirements are serious, and the line between adventure and misadventure is thin.
