Damiano Caruso wins the fourth stage of the Vuelta a Burgos, from Dona Santos to Regumiel de la Sierra.

Bahrain's Victorius, who joined the day's breakaway with six other riders, broke away 17 km from the finish and managed to break away alone. No one from behind was able to react, and the Sicilian thus triumphed by more than a minute over Rui Costa and Rui Olivera .

The main group is over 3 minutes behind, with no one attempting to break away in a straightforward finish. Tomorrow is the final and decisive stage, with the tough final climb to Lagunas de Neila.
