This queen stage across the Alps features a remarkable 4,000 m rise and drop, tucked away in the last 90 km, where the riders will tackle 3 climbs amounting to nearly 20 km each. The route climbs steadily all the way from Susa towards Turin, and then follows the gentle undulations of the Canavese to reach the Dora Riparia valley. The route then heads from the outskirts of Ivrea to the Aosta Valley to tackle the last 90 km. The stage takes in climbs up the Col Tsecore (16 km with long stretches exceeding 12% over the last 4 km), Col de St.Pantaléon (16.5 km at 7.2%) and Cervinia (19 km at 5%). The roads are always quite wide and well surfaced. Final kilometres:
the route rises all the way to the finish. The steepest stretch is encountered just before Valtournenche, and throughout the town centre. The gradient starts to weaken at the 3 km mark, with slopes averaging 1.4% over the final 2 km. The home straight (450 m long, on 7-m wide asphalt road) has a 4% gradient. Note that the route passes through two well-lit tunnels over the final 6 km. Download here the Giro 101 Safety and Security Plan.
