Bolt ready to put on a show

DAEGU, South Korea - The star of the show will make his first appearance on the opening day of the world track and field championships.

Usain Bolt, the Jamaican sprinter who has become the most recognizable name in the sport with his blistering speed and showmanship, will run in heats of the 100 meters today.

However, more world records, are not likely this time.

"People expect a lot from me," said Bolt, who set world marks in winning the 100 and 200 at the 2008 Beijing Olympics and then followed with two more at the 2009 worlds in Berlin. "Personally, I'm just focused on winning."

Bolt's first chance to win a medal will come in tomorrow's 100 final. The first medal events are set for today, in the women's 10,000 meters and marathon.

Bolt became a superstar in Beijing when he set a world record in the 100 while pounding his chest in celebration before crossing the finish line. He added a world record in the 200, and showboated before the race started off.

"That's just who I am. I like to have fun, like to make people laugh," Bolt said. "The fans like seeing me being me and trying to enjoy the championships as much as possible."

A year after those record-setting performances in Beijing, Bolt again set records in both sprints at the worlds in Berlin, running 9.58 seconds in the 100 and 19.19 in the 200. And at the 2010 Penn Relays, he ran one of the fastest 4x100-meter legs ever.

"I definitely think I will be able to run fast," Bolt said of his upcoming races.
