Bolt said Wednesday he fears his fans will get bored with him if he wins the 100 and 200 meters in 2012, and he is eager to try new events.
"I'm not going to be one of those athletes who go on to do track and field until they're 36," Bolt said. "If I win (in London) then I probably have to try something else because people are probably tired of seeing me."
"I definitely want to try long jump before I retire,'" said Bolt, the reigning Olympic and world champion and world record-holder in the 100 and 200.
After a six-week injury layoff, Bolt returns to action Thursday in the Athletissima meet, part of the IAAF's elite Diamond League series.
He will run the 100 instead of the 200 to avoid aggravating the Achilles tendon problem that has kept him out of competition since he won the 300 meters at the Golden Spike meeting in Ostrava, Czech Republic, on May 27.
"The doctor said to me I should actually try to avoid running the curves," Bolt said.
Bolt said he was still "in decent shape" despite the injury layoff, but cautioned against expecting another record-breaking result.
"My aim is to finish the race injury-free," he said.
