Barrhorn Skyrun

Barrhorn Skyrun is a mountain race of 23.87 kilometres held in Turtmann, Switzerland, in July. Runners gain 3,176 metres in total, setting off from the valley village at roughly 600 metres above sea level. The route bottoms out at 620 metres and ends on the summit of the Barrhorn, 3,610 metres up.

The climb follows the Turtmann Valley, a wild and little-visited side valley, and the altitude keeps shifting along the way. The summit is billed as the highest peak in the Alps that walkers can reach without mountaineering gear.

There is also a walking category over the same distance and height gain, aimed at people who would rather take their time and enjoy the scenery than race. A shorter Blüomatt course covers 10.22 kilometres with 1,800 metres of ascent, and it has a walking category too.
