Roberto Heras revealed that he was comfortable enough to "enjoy" the time trial that clinched him a record-equalling third Tour of Spain.
"After my 2002 defeat I was a little apprehensive at the start," said Heras.
"But this time I even managed to enjoy the ride during the final 8km when I realised that I had won."
Runner-up Perez saluted his Spanish compatriot: "Congratulations to him. He had a great Tour of Spain. It's just a dream for me to be on the podium."
Perez added: "I tried as hard as I could right from the start. I gave my all to win the stage but Roberto is very experienced and he managed things well."
