The Wildspitzlauf starts it in the village of Steinerberg, near the middle of Switzerland and not too far from Zurich. One of the longest-running trail races in Switzerland, it has been an annual event for more than three decades. About half paved road and half trails, the route climbs up from the village, alternating forest with pastures, and finishes at the grassy summit of Wildspitz. The day also features a 2 km long kids race, with 350 m of vertical and a nordic walking race 6.75km and D+ 2000m.
