This route leaves Chur on local roads but at Tamins (12km) switches to Highway 13 to Thusis, though this is not especially busy due to a parallel motorway. The route then follows National Cycle Route 6 ("Graubünden Route"), Route 6, stage 2: Thusis-Bergün.
However that website describes this section as "dangerous", mainly because it uses the 450m Passmal Tunnel (34km) and the 1.1km Solis Tunnel immediately after it, and recommends cyclists to take the train or bus between Thusis (27km) and Tiefenkastel (41km) instead. The route passes both train/bus stations.
From Tiefenkastel the route starts a very long 1200m climb to the top of Abulapass (72km, 2315m) which is followed by a fast descent to Zernez (supermarkets) and Susch.
