A tough stage across the Alps, with over 3,500 m vertical altitude gain. The route crosses the plain on relatively wide and straight roads, from Alba to Pinerolo. Then comes a lengthy but quite uncomplicated climb leading to the first pass in Sestriere (without crossing the finish line). After dropping into Cesana Torinese, the route bounces back to Sestriere through Sauze di Cesana and passes over the finish line, where KOM points are up for grabs. The course descends again to Cesana Torinese to take a second lap of the circuit, heading for a summit finish in Sestriere.
The final kilometres are raced on the wide and well-paved sp. 215, with just a short tunnel (100 m) in Grangesises, and a small roundabout 300 m before the finish. The home straight (250 m) is on 7 m wide tarmac.
