Race Overview
The Jungfrau-Marathon starts on the Höheweg in Interlaken, Switzerland, and finishes at the Eigergletscher station at 2,320 meters, below the north faces of the Eiger and Mönch. The 42.195-kilometer course runs flat along Lake Brienz for the first 10 kilometers before climbing through Wilderswil, Lauterbrunnen and Wengen, gaining about 1,953 meters overall. It draws roughly 4,000 entrants each September and enforces timed checkpoints at Wengen and the Wengernalp-Wixi junction to keep runners ahead of the mountain terrain.
