Right: view from the Furka passroad (west slope). The Furka passroad can be seen on the foreground and at the left side of the valley. The road at the background is the south slope of the Grimsel passroad. More images.|
Beating the Grimselpass
proved more difficult that expected on the basis of its gradient
profile. With a height difference of more than 1500 m between
Innertkirchen and the summit (26 km) it was our biggest and longest
climb. Moreover, the gradient profile of the Grimsel is quite
irregular, which makes it more difficult to find the right cadence.
Climbing the west slope of the Furkapass is rather straightforward, firstly a gradient of on average 7%, then a steeper, eight hairpin section, followed by an easy going final kilometer to the summit. The last 18 kilometers, downhill to Realp and Hospental were choice: not much traffic anymore, and shower and diner were close at hand. See day 4: Furka-Nufenen-Gotthard for further details.
