111 miles lay between the sprinters and one of the few sprint finishes of the 2021 Giro. The stage is flat, with just a few undulations in the central section. The route runs along the roads of the hinterland of Turin, reaches the Asti area and takes in a few short ascents (KOM points are awarded at Montechiaro d’Asti). In the second section, the stage follows flat, wide and straight roads until the finish.
The finale is nearly completely flat, with a few roundabouts and one last right-hander approx. 1,500 m before the finish. In the closing mile, the road is wide, undulating a little as the route crosses an underpass, and narrowing briefly with 700 m to go, owing to a roundabout. The finish line sits on tarmac.
