Once in a lifetime

The spectacular course can accommodate 4000 runners and sells out every year. But it’s not just about the numbers – the whole route is embedded in a breathtakingly beautiful landscape that has athletes and spectators in raptures. The Jungfrau Region is unspoilt nature at its most stunning.

The start in Interlaken reveals a clue as to where the journey ends. A glimpse of the Jungfrau, one of the iconic alpine peak trio besides the Mönch and Eiger, sets the scene. The Jungfrau-Marathon leads through constantly changing scenery: alongside the turquoise waters of Lake Brienz and through typical mountain villages such Lauterbrunnen or Wengen – all against an awe-inspiring mountain backdrop. The famous Staubbach Waterfall is also on the route.

It’s the atmosphere and enthusiasm along the course, enhanced by flag throwers, alpenhorn players and cowbell ringers, that bring this event together as a fascinating whole. The runners get a rousing reception at Eigergletscher at 2320 metres above sea level, at the foot of the Eiger, Mönch and Jungfrau.

Over 1400 volunteers are dotted along the course to hand out refreshments, provide first aid and ensure the safe and smooth running of the event.

Travel down to the valley and back to Interlaken is by aerial gondola and train. The journey directly after the run and travel to and from the event on Swiss public transport within five days before and after the event are included in the entry fee.

The marathon weekend kicks off on Friday afternoon with the runs for children, a mountain run over 4.4 km with a 755-metre climb and a Fun Run for everyone over 4.2 km. All events enable inclusion for people with a disability.
