London - Triple Olympic champion Usain Bolt has predicted he will smash his own world 100 metres record this year.

The 22-year-old Jamaican made the prediction after arriving in Manchester to take part in Sunday's street race.

He said bettering his world record of 9.69 seconds that he set in Beijing last August "shouldn't be a problem" this year.

"My coach expressed his views in Beijing, saying I could run 9.54, and I can definitely do that," he told BBC Radio 5 Live.

"I still feel goose bumps when I hear or watch the Beijing 100m, it feels good to know I've done such a wonderful thing.

"But the 100m final was just another day for me. I knew I was going to win - I was feeling good, my starts were better and that was my main concern, so I wasn't really worried.

"I don't really think about (breaking the record again) but I think it's possible if everything goes well in training."

Asked how long he hoped to remain a force in world athletics, Bolt forecast he would be a threat until at least 2015.

"I can be at the top for six years if I want," he said.

"That's the aim for me. My main goal is to make myself a legend and I'm going to work really hard to do that."
