A very challenging stage across the Southern Apennines. The start along the sea is the only flat stretch. Past Maratea, the route undulates continuously, with milder or harsher gradients. After climbing the Passo della Colla and reaching Lauria, the stage tackles the Monte Sirino. The route then hits Viggiano, clears the challenging Montagna Grande di Viggiano, and then takes in the final ascent of Sellata before reaching Potenza. Throughout the course, the roads are usually narrow and can be damaged at points, twisting continuously along the mountainside.
The final kilometres are raced entirely on urban roads. The route runs uphill across the inner city, with sharp gradients at points, and then descends along wide and well-paved avenues. There is a short tunnel at the ‑2 km marker, leading into the finish avenue. The last 350 m have an average 8% gradient, topping out at 13%. The finish sits on tarmac.
