The climb from Les Diablerets
The first kilometre is almost flat and more of a roll out of Les Diablerets. After that the picture changes quickly: from the second kilometre on the gradient stays between 6 and 9 % throughout. There is no section to catch your breath. Find your rhythm early and you can hold it almost to the top.
From the second kilometre onwards the average is around 8 %, noticeably above the 7.3 % in the fact box, because the flat start pulls the average down. The last kilometre is the steepest of the whole climb. So the hardest part comes exactly where the legs are already full. At the pass it simply stops.
How it compares to our 100 climbs

Practical tips
The Col de la Croix fits well into a bigger ride, on its own it is fairly short. A normal compact chainset is enough for the 10 % peak. The descent to Bex is much longer than the climb from Les Diablerets, because it drops all the way down into the Rhône valley. If you want to get back to Les Diablerets, ride the same road back down.
