The 42.195-kilometre (26.219 mi) course starts in Interlaken and climbs 5,960 feet (1,823 m) in elevation to the finish at the Kleine Scheidegg. The first 10 km of the course are flat. 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 race proceeds southwards to Wilderswil at the 10 km mark. From there the course heads upward through Zweilütschinen (at 15 km) to Lauterbrunnen (at 20 km). The course loops for 5 km south of the town before returning to Lauterbrunnen and then heading eastward up the alpside. It is at this point that the race is steepest, zigzagging up the hillside and climbing 450 m in the 5 km to Wengen. The course heads southeast and relentlessly upward over the Wengernalp, turning east and then northeast beneath the Eiger toward the finish. It reaches its highest point of 7,234 feet (2,205 m) around the 40 km point, and then heads steeply downhill for the last kilometre to the finish at Kleine Scheidegg at an altitude of 2061 m.
