Fiesch - Disentis-Sedrun
Now the alpine challenges follow one after the other. The route from Fiesch in Valais to Ticino - the Nufenen Pass - is the highest road pass in Switzerland. From Airolo the route descends the Leventina Valley to Biasca. From there it continues over the second busiest alpine pass of the Tour de Suisse - the Lukmanier Pass - into the canton of grisons. In Disentis, the Tour de Suisse Challenge participants turn left into the final ascent (9km) to Sedrun where spectators await the finisher for the second mountain top finish.
