The race starts from Bergamo, heading towards Val Seriana, with a short flat section before tackling a series of climbs in the foothills of the Pre-Alps surrounding the city. A relentless sequence of ascents follows, chaining together the Forcellino di Bianzano (Valle Rossa) and the climbs of Ganda, Colle di Berbenno, and Valpiana. This first set of climbs covers over 50% of the total elevation gain of the race. A short flat segment leads to the Lake Como area, where the racecourse runs alongside the lake from Lecco to Onno. Here, the race turns and tackles the ascent to Asso (known as “la Onno”) and then the legendary Ghisallo, though from its less grueling side. The riders will then descend to Bellagio and tackle a fast-paced stretch along the lakeshore to Nesso. Once there, the hardest climb of the Lombardia begins, namely the ascent to the Colma di Sormano. This 13-km climb features gradients up to 11%, on a sometimes narrow road with numerous hairpins. After cresting, a rapid descent with switchbacks takes the riders down to Maglio. From here, the route trends gently downhill to Como. Once past the city, the riders face the ascent of San Fermo della Battaglia (397 m), before descending back into Como heading towards the finish line.
Last kilometres
The final 10 kilometers begin within the city of Como, following wide boulevards until the railway underpass, where the final climb of San Fermo della Battaglia starts. The gradient hovers around 7%, peaking at 10%, on a narrow road with a rough surface. The riders will navigate several hairpin bends before cresting at around 5 kilometers to go. The descent unfolds on a wide, well-paved road, featuring two well-lit tunnels and two large roundabouts, ending with around 1 km to go. At 600 meters to the finish, there’s a sweeping left-hand corner. The finishing straight is on asphalt, with a 7-meter-wide road.
