Stage 20 - Saturday, May 31: Rovetta - Tirano, 224km

The Giro's penultimate day should offer one last chance for the mountain men to change the overall classification. The 224-kilometre run will cover the Passo Gavia, the super-steep Passo del Mortirolo and the infamous Aprica before arriving in Tirano.

The Corsa Rosa will celebrate 20 years since the snow covered day on the Passo Gavia that Erik Breukink won and Andy Hampsten put in his blow for the eventual overall win. The 2618-metre pass is this year's Cima Coppi – the highest point of the Giro – and will lead to the Mortirolo and Aprica, which was last seen as the bitter fall-out between Gilberto Simoni and Ivan Basso in 2006.
