From Bourg d'Oisans [Average gradient:
5.8% - Maximum gradient : 8.6% - Distance 11.1km - Height gain
Approximately 5 km from Bourg d'Oisans is the start of the
climb to the Col d'Ornon (last used in the Tour de France in 2002).
This climb although never steep is harder than it looks which is
probably due to the long straights (a rarity in the Alpes).
Throughout the climb you very much remain in the valley and
this gives the climb a slightly intimidating feel. The road
surface is good and the gradient is never too steep so makes a
perfect cycle climb for tired legs.
