Cycling stops in Stelvio

The Stelvio is the most theatrical road in cycling: a wall of numbered tornanti stacked up the Prato side of a 2,758 m pass, each bend signed like a countdown. No summit has been the Giro's Cima Coppi, the prize for the race's highest point, more often.

Twenty-four kilometres and 1,834 metres of climbing from Prato, with forty true hairpins among the forty-eight painted numbers, because the paint counts the gorge's gentler corners too.
