Col de l'Iseran

 

The Col de l'Iseran is the highest paved mountain pass in the Alps with its breathtaking 2.770 metres.
It is part of the French Graian Alps and belongs to the Route des Grandes Alpes. It connects the Isère Valley and the Arc River Valley between Val-d'Isère in the north and Bonneval-sur-Arc in the south.
Starting from Bourg-Saint-Maurice, you climb 2.045 metres over a distance of 46,9 kilometres, pass a number of galleries and tunnels, and have to overcome a maximum grade of 9,5 percent. It's fortunately not everywhere so steep; the average slope is just above 4 percent. 

The Col d'Iseran was first used in the Tour de France in 1938 and the first rider over the summit was Felicien Vervaecke. One year later, in the tour of 1939, the first mountain time trial was introduced over the Col d'Iseran, which was won by Sylvere Maes by a margin of four minutes.

Since 1947 the pass has been used four times in the Tour de France. It was scheduled to be used in 1996, but was left out at the last minute due to bad weather. As a result of snow on both the Col de l'Iseran and the Col du Galibier, the scheduled 190 kilometres stage was truncated and reduced to a 46 kilometres sprint from Le-Monetier-les-Bains which was claimed by Bjarne Riis.
