TARRAGONA, Spain -- World champion Philippe Gilbert won the 12th stage of the Spanish Vuelta on Thursday, and Vincenzo Nibali retained the leader's jersey.
Gilbert, a Belgian riding for BMC, caught Edvald Boasson and moved past him in the final yards to cross first in the 102-mile stage from Maella to Tarragona on the Mediterranean coast.
Nibali provisionally maintained a 31-second lead over Nicolas Roche.
The 13th stage Friday remains in the northeastern region of Catalonia for a second straight flat stage, a 105-mile route from Valls to Castelldefels.
The three-week race then heads back into the mountains for a trilogy of stages in the Pyrenees.
