Britain's David Millar won the world time trial crown in Hamilton, Canada on Thursday.
Millar coasted to victory ahead of Australia's Michael Rogers
The 26-year-old Scot, second to Jan Ullrich in Lisbon two years ago, covered the hilly, sun-drenched course in 51 minutes 17.29 seconds.
Australia's Michael Rogers came second in 52:42.38, with Uwe Peschel of Germany third.
The last Briton to win the world crown was Chris Boardman who won the inaugural event in 1994.
"I've been so scared of not winning the past ten days that right now it just feels more of a relief," said Millar.
"I felt more like a junior this past week. I spent a lot of time studying the course.
"I decided I would keep the same rhythm until the finish, then when I saw the gaps I had at the intermediate points I even began to slow up a bit."
Setting a fast pace from the off, Millar reached the first time check more than seven seconds ahead of his nearest challenger.
By the 20km mark, he was over 36 seconds ahead of the pace and caught Isidro Nozal of Spain, who set off a minute and and a half before him.
Millar has previously gained stage wins in the Tour de France and Vuelta, and the Scot is already looking forward to taking on the world's best in Athens next year.
"Obviously it would have been fun to race against Jan here but I think the standard of the guys already is so good that it doesn't really matter," said Millar.
"It's got to the point where I'm not scared of Lance Armstrong and Jan in a time trial, and in a one-day race it's totally different from doing it in a big stage race.
"But I'll be the one to beat at the Olympics in Athens next year."
Nicole Cooke could earn a second gold for Britain in the women's road race on Saturday.
