World's fastest man Usain Bolt does not believe his record-breaking days are over just yet and has targeted the possibility of lowering the 200m mark, perhaps as early as next year.

In fact, the double record holder over the 100m and 200m distance, believes lowering the half-lap mark would be a more phenomenal achievement than claiming gold medals at the next Olympic games.

"Forget making the next Olympics and the medals, breaking that time would be an ever bigger success. I'd love to crack it, knowing that people were sitting in their homes and losing their minds at my achievement," Bolt said.

The 27-year-old sprinter, who set both marks four years ago at the World Championships in Berlin, admits that lowering the marks will get harder with age and it would take pretty much a perfect season.

"To reach that landmark pace, I would need to have the perfect season, like the one I had in '08. I think next year could be my shot at it, though the window of opportunity is getting smaller with every campaign. The older I get, the narrower that window becomes; the harder it is for me to reach peak fitness in time for a major race."

The runner is confident, however, that the window to still achieve the feat has not closed, and believes he is still the man to get it done.

"I don't think it's totally out of reach in the next season or so. Seriously, who would be surprised if I did it? Who's going to stop me from going fast?
