Route
The stage opens with a flat first section in the Dora Riparia valley, which the race follows to the outskirts of Susa, where the ascent of the Colle delle Finestre begins. The Colle delle Finestre (Cima Coppi) features an almost constant gradient of 9.2% from bottom to summit, aside from a brief ramp in Meana di Susa peaking at 14%. The first 9 km are paved, while the following 9 km are unpaved gravel roads to the summit. Along the paved section, riders encounter 29 hairpins in less than 4 km (45 in total to the summit). The descent is highly technical, narrow and exposed in its opening section down to Pian dell’Alpe. Once back on the SS23, the climbing resumes at manageable gradients all the way to the finish.
 
Final kilometers
The final kilometres take place entirely on the SS23, on a gentle uphill gradient (average 5%) along a wide and well-paved carriageway. Final straight: 400 m on 6.5 m-wide asphalt.
