The International Rigi Mountain Run is perhaps the best-known in the series of events that comprise the central Switzerland trail race series, drawing over 300 runners each year. The run begins on paved roads in the town of Arth on the shore of Lake Zug, and finishes atop the popular Rigi Kulm. The event is one of the older trail races in the region, too, having first been held in 1984. The International Rigi Mountain Run is a steep push, climbing nearly 1,400 meters in just over 11 km, on a mix of roads and paths. The reward, however is not insignificant– arriving at the summit of the Rigi, with stunning views of central Switzerland.
