Road cycling
A challenging and relentless climb, like a good military road, it climbs with very regular gradients that allow, once you find your rhythm, to easily reach the summit.
From Pré-Saint-Didier:
A decidedly easy climb to La Thuile (gradients of 4-5%), from there the climb becomes challenging with steep gradients (though not as steep as those on the more famous Morgex side).
Be careful, in summer, of traffic (use extreme caution on both sides when descending) and the southern exposure, which makes it very hot in the afternoon.
