Road cycling
Challenging and relentless climb, from a good military road it ascends with very regular gradients that allow, once you find your rhythm, to go steadily to the top without too much trouble.
From Pré-Saint-Didier:
Decidedly easy climb to La Thuile (gradients around 4-5%), from there the climb becomes challenging with severe gradients (although not like those of the more famous Morgex side).
Be careful, in summer, of traffic (on the descent, use great caution on both sides) and of the south-facing exposure which makes it very hot in the afternoon.
