The BikeTicket2Ride Tour is a signed route with an accompanying GPS track that allows the rider to tour around the entire Chur/Churwalden/Lenzerheide/Arosa region with a series of lifts, descents, pedal climbs, and tons of Singletrack.
The tour can be conducted in a variety of lengths and difficulties, but I personally completed the Black route--the longest and most difficult. Despite being pretty long and technical, with all of the lift rides up the mountain, many riders in halfways decent shape should be capable of completing this tour.
