Departure from Como heading towards Cantù. The riders will tackle the Ghisallo from the Asso side, descending to Bellagio and reaching Lecco along the shore of Lake Como. Once inside the province of Bergamo, the thrilling series of climbs leading to the finish line begins, featuring a non-stop succession of ups and downs with hardly any flat stretches. The first climb is the Roncola (Valico di Valpiana, gradients up to 17%), followed by Berbenno, Dossena, Zambla Alta and Passo di Ganda, bringing the total elevation gain up 4400 m. From Ganda, the athletes will reach Selvino, where the traditional long descent with its 19 hairpin bends will begin. Once in the valley, the town of Bergamo will be hit after 9 flat km (the only flat ones in the entire finale), featuring the traditional passage through stunning Città Alta (upper town) heading to the finish line in the centre of the city.
The last kilometres through Bergamo Alta climb steeply to Porta Garibaldi and Colle Aperto, with 200 m in cobblestones. The gradients are initially above 10% (max 12%). On the way down, the road is wide with a smooth surface. At 1800 m from the finish line, there is a sharp turn with a short bottleneck to get past Porta Sant’Agostino. A wide bend to the left will then take the riders onto the 800 m straight leading to the finish line: width 7.5 m on a slightly downhill asphalt surface in the first part and flat in the end.
