I'm on track for legend status - Bolt

Jamaican Usain Bolt, who shattered the 200 metres world record to win gold at the world championships on Thursday, said he was closing in on his biggest aim of becoming a sprinter the world would never forget.

"I keep telling you guys my aim is to become a legend. I don't think about records. I know what to do and I go and execute," he said.

"I did well for myself and I am on my way to becoming a legend so I am just happy."

Bolt claimed three gold medals at the Olympics last year and two at these World Championships in Berlin, smashing the world records on his way to every title.

In the same stadium where American Jesse Owens won four gold medals, including three in the sprints, at the 1936 Berlin Olympics, Bolt knocked off 11 hundredths of a second in each of his two gold medal races, the 100 and 200 metres.

He ran a jaw-dropping 9.58 seconds in the 100 before pulverising his 200 mark with a new world record of 19.19.

"I keep saying anything is possible. You work hard, you train hard. I still train very hard and running fast races doesn't change that," he said.

Bolt said he was not interested in convincing those who did not believe the records were a result of his hard work, saying that questions about doping were an inevitable part of athletics.

"I am not worried. I don't get offended," he said.

"I know it is going to be always like this in the sport."

Asked whether a knighthood from Queen Elizabeth would be something he would like, Bolt said: "I just say that would be a great thing.

"I would get the title 'Sir Usain Bolt'. That sounds very nice."

Meanwhile, world record holder Mike Powell said Bolt could jump nine metres in the long jump.

Powell, whose world record of 8.95 metres has been standing since 1991, said Bolt should try out long jump, a perfect fit for his speed and height.

"I can show him how to jump nine metres, for a small fee," he said with a grin.

"With his height (1.95m) he is the type who would scare me (as a long jumper)... he is tall and fast. You cannot put into words how great an athlete he is."
