Sprint superstar Usain Bolt says he is ready to deliver "great things" at this year's London Olympics.
Sprint superstar Usain Bolt transformed the world of athletics with a stunning set of world record-setting performances at the 2008 Beijing Olympics.
The Jamaican went on to better his double sprint records at the Berlin worlds a year later, but insisted on Wednesday that he would be ready to deliver more "great things" at this year's London Games.
"It's the Olympics, I'm going there to do great things," said Bolt, who opened his season on home soil earlier this month with a 9.82 seconds over 100 metres and kicks off his European season in Ostrava, Czech Republic on Friday.
"I want to repeat what I did in Beijing," he said, adding: "If I'm in great shape, no one'll beat me in London, that's for sure."
Bolt, who lost his world 100m title to compatriot Yohan Blake in Daegu last year after false starting in the final, added: "I'm working hard, things are coming together smoothly.
"I'm trying to stay focused and I know I'll get there. I expect to run fast, that's the expectation I have of myself."
Bolt insisted that setting world record times were not as important as claiming gold.
"You can't say," he answered when asked what time he expected to win the 100m. "You never know what the temperature will be, you never know what will happen on the day.
"I'll run as fast as possible to get across the line first. I'm not really worried about the time."
Bolt stressed that he had been forced to take stock after his stunning false-start in Daegu last July, which left fans shell-shocked as one of the world's most recognisable sporting figures was led off the track.
"One thing I learnt about my false start in Daegu is that I definitely need to be myself," he said.
"I went through the season doing bad starts, but it came together in Daegu. I was anxious because I was doing so well and I lost focus.
"In the 200m, I went right back to being me and there was no problem. I'm over that because I know why I false started. It won't be a factor."
