Giovanni Visconti takes a tumble whilst sprinting for KOM points at the Giro d'Italia (video)

Giovanni Visconti (Movistar) hit the deck during stage 13 of the Giro d'Italia as he challenged Damiano Cunego (Nippo-Vini Fantini) for the king of the mountain points.

As the two riders went head to head at the top of the classified climb, Visconti's bike slid out from under him. The summit was located on a bend, which was populated by soigneurs on the road and fans hanging over the barriers.

The 33-year-old was able to get up and continue riding (and eventually finished second on the stage), but later footage showed he was still suffering the outcome of the crash later in the stage.

With Visconti up the road and Andrey Amador in second on GC, the Movistar leadership question remains. Alejandro Valverde, nominated leader and expected overall challenger, is in a strong position and we should see him coming to the front as the race continues.

Stage 13 saw a shake-up of the general classification with the race taking in four classified climbs. Bob Jungels (Etixx-Quick Step) slipped out of the race lead with Amador moving from second into the maglia rosa.
