LONDON Jamaican Usain Bolt hardly had to break sweat on Wednesday as he coasted into the men's 200 meters final where he will bid for an unprecedented Olympic sprint double-double.
Bolt, 25, will be joined in Thursday's gold medal showdown by compatriots Warren Weir and his most likely title rival Yohan Blake, as well as America's one representative Wallace Spearmon.
"I'm ready. This is my favorite event so I'm looking forward to it," Bolt told reporters after blitzing the first 100 meters to allow a gentle jog on the home straight for a heat- winning time of 20.18 seconds.
"You can't work too hard, you've got the finals. That was the aim, you can't push too hard."
The world's fastest man sped to the 100m and 200m titles in Beijing in 2008 and on Sunday secured the former event once more in scintillating style. Victory in Thursday's final would make him unquestionably the sport's greatest ever sprinter.
Asked if he could break the 19.19 seconds world record he set in Berlin in 2009 Bolt said: "It's a possibility. I can't say but the track is fast so it's going to be a good race."
The lanky Jamaican said he had wanted to push himself through the bend, resulting in a blistering opening pace.
Although Spearmon, who finished third in Beijing in 2008 but was then disqualified for stepping out of his lane, is likely to battle it out with former European champion Christophe Lemaitre for bronze, Bolt did not rule out a Jamaican 1-2-3.
"It's going to be hard. Wallace Spearmon is there and he's been there before," said Bolt, who even managed a smile to camera once he was in the blocks at the start of his race.
"There's a lot of people there who are going to come and try and spoil the party so we'll see," he said, adding that he had managed to do some skipping in the warm-up area having had his rope confiscated before Sunday's final.
Weir, 22, is also coached by Glen Mills, just like Bolt and Blake.
The year's fastest man Blake called the race "a walk in the park" after setting the night's best time of 20.01 despite slowing up in the final 100m with Spearmon and Lemaitre chasing.
Spearmon, though, said it had been slightly harder than that for everyone else: "We had a tough one. We couldn't jog 20.1 (seconds) like some other guy. We were running."
European champion and Olympic 100 meters finalist Churandy Martina of the Netherlands also qualified.
Even some of those who did not make the final enjoyed running with the world's greatest sprinter.
"It's an honor to run in an Olympic Games, Brazil's Aldemir Da Silva Junior said. "It's special to run here, with Usain Bolt, the best in the world, in a stadium like this."
