technical info
The stage starts flat until the Canavese region, then a series of increasingly tough climbs lead into the Valli di Lanzo. After Viù, the Colle del Lys climb begins. A descent brings riders into the Dora Riparia Valley to Susa, where the Colle delle Finestre (this year’s Cima Coppi) climb begins. The Finestre climb averages a consistent 9.2%, with a 14% ramp in Meana di Susa. The first 9 km are paved; the final 9 km are gravel. There are 29 switchbacks in less than 4 km (45 total). The descent to Pian dell’Alpe is narrow and exposed. The final climb to Sestriere on the SS23 is steady and manageable.
Final kilometres
Final kilometres are all on the SS23, a steady climb at about 5% on a wide, well-paved road. Final straight: 400 m on 6.5-metre-wide asphalt.
