The first summit finish comes after a short yet full mountain stage. After the first 20 km on flat roads, the route starts to climb along easy to mild gradients for almost 40 kilometres, including a deceptive false-flat drag before the ascent. The route then descends along wide roads, yet worn out at points. From km 75 to km 135, the stage course runs along wide, fast and mostly straight roads, with a number of tunnels in the final stretch. After the Castel di Sangro intermediate sprint, the route takes in the final climb leading to the finish. The final climb is 17 km long, with an average 4.8% gradient. The first part is quite steep, with a short 12% stretch, followed by a deceptively false-flat drag (across the centre of Roccaraso). Seven kilometres before the finish, the route starts to climb again with variable slopes ranging from 4% to 7%. The final km has a 7% gradient. The home stretch, running entirely uphill, is 120 m long, on 6-m wide asphalt road. Giro d'italia comes back to Roccaraso after 29 years: in 1987 Moreno Argentin won the stage from Rieti to Roccaraso.
