Usain Bolt, the fastest man on the planet, has won every major sprint event there is, including the Olympics gold medals in the 100m and 200m events, which he won during the 2008 Beijing and 2012 London Games.

However, Bolt will be eager to complete his hat-trick of Olympic gold medals in the 2016 Rio Olympics as well.

Bolt, who has been consistently performing at top level, has been hard done by injuries in the last couple of years that kept him out of some events. Bolt's coach Glen Mills understands the athlete like no other and feels that after the Rio Olympics, retirement beckons for the 100m and 200m world record holder.

"We are going all out to give the Olympics one last fling and after that retirement beckons. If he gets through this Olympics I don't think he will be able to continue at this level because you can see that it's now beginning to affect him more than before," Jamaica Gleaner quoted Mills as saying.

Bolt has been the best sprinter in the world for a long time, ever since he came up with an incredible world-class performance in the 2008 Olympic Games in Beijing. Mills feels there are challenges in order to get Bolt to perform at his maximum level.

"Bolt is probably the greatest talent in sprinting that he world has ever seen but that said, getting him to be able to perform at his best level has its challenges. It's like there is a diamond in a particular area but to get to it or to get it out, there are a lot of dangers to be encountered."

But one can count on Mills to get the best out of Bolt in the 2016 Olympics as well.

One might be stunned to hear, but Mills wants Bolt to break the 200m record once again, which currently stands at 19.19. His 100m record of 9.58 might be impossible. But if he stays in perfect shape and fitness, he might well achieve it.

"I'd love to see it again (world record), I don't think it's out of the realm of possibility but he needs to stay healthy, significantly long enough to be able to train the way he needs to train in order to achieve those performances. He wants to run sub-19 before he goes and we will try for it," said Mills. "He doesn't speak about the 100m (9.58) because it will be much more difficult for him to run that 9.58 but it is possible for him (200m world record)."

Though it might be a huge task for an athlete to run a sub-19 in the 200m, Bolt can take his game to the next level when he wants to. The recent world championships in Beijing is a perfect example. The Jamaican was expected to be the second best to Justin Gatlin in the 100m and 200m sprint event, but the sprinter silenced his critics with an amazing run in both the events.

So with Bolt, anything is possible.
