Spaniard Roberto Heras completed a record fourth Tour of Spain victory in Madrid on Sunday.
Heras successfully defended his Vuelta crown
Victory in the 21st and final stage went to Italian sprint specialist Alessandro Petacchi - his fifth win of this year's Vuelta.
Home favourite Heras, 31, won the sixth and 15th stages, taking the overall lead after the latter, and survived a heavy fall during stage 12.
Russian Denis Menchov was second, with Spain's Carlos Sastre third overall.
German Erik Zabel was runner-up to Petacchi on the stage, with his compatriot Heinrich Haussler third.
Heras, who won the Tour in 2000, 2003 and 2004, finished comfortably in the main pack.
Switzerland's Tony Rominger is the only other rider to have won the Spanish event three years in a row.
Heras said: "I felt really good this year, even if I had a couple of doubts
when Menchov won the 14th stage as he was going extremely strong.
"I reckon of all four Vuelta wins this is the one where I felt in the best form."
Next year, Heras is expected to lead Liberty Seguros in the Tour of Italy.
"I've done everything I can do on home territory and racing abroad more may be my best way ahead for me," he added.
