This 16km course takes place in the German speaking Swiss Canton of Bern. It is roughly two-thirds trail and one-third road, and runs up the stunning Kien valley, in the UNESCO Berner Oberland World Heritage site. It finishes in the tiny, high Alp village of Griesalp. The race can be run as a relay, and there’s also a category for Nordic walkers (9km, 456m).
