The 2007 edition of the competition incorporated the World Long Distance Mountain Running Challenge and attracted 4200 participants from 50 countries.

The race begins in central Interlaken and circles around the town centre before moving east to Bönigen, where runners briefly run along the shore of Lake Brienz.

The course loops for 5 km south of the town before returning to Lauterbrunnen and then heading eastward up the alpside.

The course heads southeast and relentlessly upward over the Wengernalp, turning east and then northeast beneath the Eiger toward the finish.

It finishes at Eigerletscher at an altitude of 2,320 m.[3] Shortly before leaving the moraine and turning towards the final ascent, the runners are traditionally greeted by a bagpipe player.
