FLORENCE, Italy -- Tony Martin of Germany won his third straight title in the individual time trial at the road cycling world championships with a dominating performance on Wednesday, while Olympic champion Bradley Wiggins finished a distant second.
Martin completed the flat 35.5-mile route from Montecatini Terme to Florence in 1 hour, 5 minutes, 36.65 seconds. Wiggins, of Britain, finished second, 46.09 seconds behind, and Fabian Cancellara of Switzerland was third, 48.34 behind.
Cancellara won the event a record four times, in 2006, `07, `09 and `10. Martin is the second rider to win three straight after Michael Rogers of Australia accomplished it from 2003-05.
"The first title is always the nicest, but this comes pretty close," Martin said. "Now I have a lot more pressure on my shoulders."
After crossing the finish and hugging his team supporters, a joyful Martin dropped to the road on his back and gave a wide smile.
"It was really emotional for me," he said. "The last years gave me a lot of experience. I had to work with the pressure and to use the pressure as more motivation."
Vasil Kiryienka of Belarus finished fourth and Taylor Phinney, the American who finished second last year, was fifth.
The only uphill section of the course was a 1.24 mile stretch shortly after the start. That made it ideal for TT specialists capable of maintaining their aerodynamic position crouched over their handlebars for more than an hour at full speed.
Conditions were perfect, with the course bathed in Tuscan sunshine, and fans came out in large numbers as the route took riders past Florence's historic monuments like the Duomo cathedral.
The most technical section came just before the finish, with a series of sharp turns along Florence's medieval streets.
Martin trailed Cancellara at the first checkpoint but seemed to grow stronger as the race progressed. By the time he reached the historic center, the German rider was pretty confident he would win.
"The old town was nice, but I was more focused not to crash. You really needed to concentrate after one hour on the limit," Martin said. "I almost didn't feel the pain anymore."
Martin's average speed was 32.88 mph.
Martin has won nine of 12 individual time trials this year, including one at the Tour de France. He also powered Omega Pharma-Quick Step to victory on Sunday in the team time trial at worlds -- in another title defense.
For Wiggins, the silver medal capped a somewhat disappointing year.
In 2012, Wiggins became the first British rider to win the Tour de France. He missed this year's race due to injury and illness after also withdrawing from the Giro d'Italia midway through.
Wiggins won the Tour of Britain this week in a sign of improved form. But Chris Froome, this year's Tour de France winner, will lead Britain's team in Sunday's road race.
"I feel pretty relieved now that it's over," Wiggins said. "I'm pretty satisfied to come away with the silver medal. There's not that much more I could have done. I was just beaten by a better bike rider today."
Dutch cyclist Ellen van Dijk won the women's individual time trial on Tuesday.
With no races on Thursday, the next events are the junior women and under-23 men's road races on Friday.
The worlds end Sunday with the featured road race over a 169-mile route that starts in Lucca near the coast and ends with 10 laps of a hilly circuit in and around Florence.
