Inferno Half marathon / Relay race


Distance 21.097 km, Inclination 2175 m.
Lauterbrunnen (795m a.s.l.) - Mürren (1640) - Schilthorn (2970).

The start is at Camping Jungfrau, directly below the Staubbach Falls, the landmark of the Lauterbrunnen Valley.  The first 11 kilometres appear fairly “harmless”, with a climb of around 800 metres, merely a warm-up. After the Sports Centre, it’s straight down to business. The Höhenlücke is the first wall to stand in the way of the “mountain goats”. After the Kanonenrohr (Cannon Barrel), which is two grades steeper, a 2km level stretch of scree awaits athletes before they tackle the steep 1.5km final climb of 400 metres to the Schilthorn summit.
