Over the last 150km of this Queen Stage across the Dolomites, there are six passes to be climbed, for a total rise and drop of 4700 metres (out of 5400 metres).
The route runs across the Val Cordevole along well-surfaced roads, all the way to Arabba. The route then clears Passo Pordoi, followed by Passo Sella and Passo Gardena and heads for the first pass over the finish line in Corvara.
The road then climbs up Passo Campolongo, Passo Giau (the harshest climb of the stage, with an average 9 per cent gradient, and peaks of more than 10-12 per cent over the first kilometres) and Passo Valparola, which leads to the final 5km. All climbs and descents feature hairpins and narrow urban crossings.
The last 5km runs mostly uphill. The route clears Muro del Gatto (360 metres, with gradients ranging from 13 to 19 per cent), and then drops down into the road leading to Corvara, still climbing slightly at 2-3 per cent. The last bend is 150m from the finish line and the home stretch, on a six metre wide asphalt road which has a slight uphill gradient.
