A short but intense stage, which leaves little time for the riders to catch their breath. The overall elevation gain, when compared to the stage length, is worthy of an Alpine stage. The opening kilometres from Santena to the foot of the first climb are the only flat stretch of the stage. The route ascends from Rivodora to Superga, taking in two laps of a 36.4‑km circuit that includes climbs up to Superga and the Colle della Maddalena. The former is 5 km long, with gradients hovering around 10%, and topping out at 14%. The latter is much shorter; it winds its way along a narrow road across the woods, with maximum 20% gradients. A technical descent then leads all the way to the finish.
After clearing the Colle della Maddalena, the route drops into Valsalice, with some challenging bits as it passes through urban areas. The gradients then go up again, up to Parco del Nobile. The last 4 km run entirely downhill, mostly on narrow roads. The road then opens out past the last kilometre, in urban Torino, and levels out with approx. 700 m to go. The home straight is on tarmac road.
