This ride starts in Valserhone, France and enters Switzerland near its westmost point. After visiting Geneva, Lausanne, Fribourg and Interlaken it then climbs a series of high mountain passes (Grimselpass, Furkapass, Oberalppass, Albulapass) before leaving Switzerland near its eastmost point and ending in Landeck, Austria.
Stage 4 is an optional loop which climbs the Grosse Scheidegg pass south of Interlaken.
After passing through the middle of Geneva the route follows the north shore of Lac Leman, mostly on the coast road (which has fairly decent cycle lanes or tracks much of the way).
The route starts near Valserhône station and ends in the suburbs of Lausanne at Hotel SwissTech on the EPFL university campus.
The route starts at EPFL just west of Lausanne and ends at ibis budget in the northern suburbs of Fribourg.
The first 33km to Meiringen is pretty flat, on fairly quiet roads. The climb to the Grosse Scheidegg is on a fairly narrow, minor, road but with quite a lot of tourists in cars. However after Schwartzalp (47km) there is a 12km section over the summit where most cars are prohibited. After Grindlewald the route follows the main road, which probably is what the rider wants as they can go quite fast.
The first 64km to Ilanz is on Highway 19. After that the route follows minor roads.
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.
The remaining 37km is in Austria, along minor roads and cycleways all the way to Landeck.
