Races over various distances and in a number of categories will appeal to mountain runners, trail runners and “fun runners” alike. The ultimate challenge and blue ribbon event is the new K68, the successor to the much loved K78. The K68 race will start at the same time as the K43, at 8am on 25 July 2020 in Davos. The well-established and very popular K43 is unchanged. Runners who favour altitude over distance can take on the K20 (2,590 m asl) which features an ascent of Jakobshorn. The K23 from Klosters to Davos and the K10 to Clavadel round off the multifaceted series. Participants will enjoy great support from spectators and musical groups lining the routes.
