Matterhorn Ultraks
Four courses of varying distance and difficulty: «Active», «Mountain», «Sky» and «Extreme» and difference in altitude of up to 3,600 m, which is the equivalent of 90 kilometres. In addition there is also a «Vertical» race (Vertical Zermatt Sunnegga). This allows each runner to find the run that suits him. There is also a race for the children.
