A mixed-terrain stage, undulating particularly in its second part. A departure from Camaiore leads the riders across the Pisan plain to Volterra, touching on Pisa, Ponsacco and Lajatico. The group will then enter the surroundings of Siena, with a series of ups and downs of varying degrees of difficulty until the riders reach Colonna di Montarrenti where a circuit of sorts begins. The race will pass through Rosia and, after a short stretch on the ss.223, will climb the hill of La Pineta before passing through Monticiano and reaching the San Galgano plain. Another climb to Chiusdino follows and then a short climb (Frosini) back to Colonna di Montarrenti. The riders pass through Rosia once more to reach a flat finish.
The last few kilometres are virtually flat. There is a slight descent initially, followed by a slight ascent up to the finish. The last bend is situated about 3km from the finish. Arrival on asphalt, 7m wide roadway.
