However, track and field's poster boy is convinced that he still has it in him to go even faster than the 9.59 and 19.19-second world records, and says that he is looking forward to getting up to top speed in the upcoming season, after suffering an injury recently.
The 27-year-old, who resumed training at the weekend after his manager Ricky Simms reported that his foot was sore a few weeks ago, also underlined that he is not bothered by the setback, adding that he expects to be back to his best soon.
"(The injury) is nothing serious ... my experience has taught me that that's just the nature of the sport," Bolt told The Gleaner. "Setbacks are a part of track and field. I have come to accept that a long time ago. I had mine, and (I'm) now back in training preparing for the upcoming season."
Bolt had his closest brush with his 9.58-second 100m world record in the final at the 2012 London Olympic Games, where he won the gold medal in 9.63, the only time he has gone below 9.70 since 2009, with season best times of 9.82 (2010); 9.76 (2011) and 9.77 last year. In the 200m, the sprinter ran 19.32 seconds in 2012 but has gone 19.56 (2010), 19.40 (2011) and 19.66 (2013) since running 19.19 in Berlin.
If he is to lower the marks, he will need to be at his best, but the five-time IAAF World Male Athlete of the Year is fully confident that he will set new marks before his time in the sport is done, particularly after the encouragement of his coach.
"I have discussed with my coach what it will take to lower these records, and he thinks it's very possible," said Bolt, who is coached by Glen Mills at the Racers Track Club. "I trust my coach completely, so if coach Mills says they can be broken, then I know I can lower them."
posting strong times
Bolt added that he is looking forward to posting strong times this season and believes that Jamaica stands a good chance of breaking the Santa Monica Track Club's 1:18.68 4x200m world record at next month's IAAF World Indoor Relays in The Bahamas.
"(The IAAF World Relays) should be a lot of fun," Bolt said. "Relays are always the best part of any championship for me."
"Jamaica has a lot of talented athletes, so I have no doubt that we can lower the (4x200m) record," he added, without confirming whether he will actually be able to compete at the May 24 and 25 championships.
Nonetheless, with three major championships on the cards for the next three years - next year's IAAF World Championships in Beijing, China; the 2016 Olympic Games in Rio and the 2017 IAAF World Championships in London - Bolt is also focused on regaining his fitness and staying injury free.
"I just want to run some fast times and finish the season injury free so I can focus on these three major championships coming up," Bolt said
