The Muro di Siena, or wall of Siena, is the beautiful finale of the new cycling classic Strade Bianche, which is partly driven on unpaved "white" roads.
The actual climb starts just outside the walls of the old town at the Porta di Fontebranda at Cafe Blandis. From there it goes over steep cobbled streets to the large beautiful central square of Siena, Piazza del Campo,
where the local districts compete twice a year in the Pailio horse race for local honor.
But you start climbing a kilometer earlier, as soon as you leave the ring road around Siena. Where the gradients are still moderate, it's steep from the city gate. The last hundreds of metres rise by an average of 13% to a maximum of 16%.
Starting from Siena,
the Muro di Siena - Via Santa Caterina ascent is 0.491 km long. Over this distance, you climb 59 heightmeters.
The average percentage thus is 12.02 %.
The maximum slope is 18%.
