alternate between Bergamo and Como. Race characteristics The Giro di Lombardia is considered a climbers classic and one of the most arduous races of the season, because of its distance (ca. 255 km) and several famous climbs. Nowadays the route usually features five or six significant climbs. The best-known of them is the Madonna del Ghisallo, one of the few fixed locations of the race. The climb is 10,6 kilometres long, with an average gradient of 5.2% and stretches of over 10%. Because the race usually has a downhill or flat run-in to the finish, the main contenders are riders with a broad range of skills. As such, the course favours climbers with a strong sprint finish and even Grand Tour specialists. Time trial specialist Tony Rominger won the Tour of Lombardy twice in the 1990s and Tour de France winner Vincenzo Nibali won the 2015 edition after a downhill attack on the penultimate descent. The race is often compared to Liège–Bastogne–Liège, the monument race in Belgium earlier in the year. Both classics have a similar hilly course and show a similar palmarès since the 1960s, but are different in character. The hills in Lombardy are usually longer than those in the Belgian Ardennes and are more spread out over the course. Liège–Bastogne–Liège has 12 categorized climbs, usually shorter and steeper, coming in faster succession than in the Tour of Lombardy, and has an uphill-finish. Because of its position in autumn as one of the last classics of the year, the race is commonly nicknamed the Race of the Falling Leaves. Consequently, the weather repeatedly plays a decisive role in the nature of the race. In bad weather - common to mountainous Lombardy - the race is often a grueling contest where the strongest riders attack well ahead of the finish. The editions of 2006, 2010, and 2012 were exceptionally rainy. In 2010 Philippe Gilbert and Michele Scarponi attacked with 40 km to go; Gilbert distanced Scarponi on the San Fermo della Battaglia and won the race. In 2012 Gilbert crashed on a wet descent. When the weather conditions are good, teams are able to control the race more easily and decisive attacks come later in the race. On sunny days, the leaves on the trees typically blaze a golden trail around Lombardy, and TV coverage displays extensive aerial footage of the scenery around the Como Lake. The Italian press,
