Jamaica's superstar sprinter Usain Bolt, known as the fastest man on earth, aims to win the gold medal for the third time in the 100m at the Rio Olympics. Bolt is one of the most decorated athletes in the history of the Olympic games..

He won the 100m sprint in both the 2008 Beijing and 2012 London Olympic games. He also picked up gold in the 4X100 relays at the last two Olympics.

"Just to defend my titles, to do the threepeat. That's my main goal, that's my main focus. My secondary goal is to try and run sub-19, that's something I really want and I hope that everything goes smoothly and I can get it. That would be a big step for me," said Bolt, as quoted by Reuters.

The 29-year-old, who has suffered from a string of ankle injuries, feels he is yet to get back to his best and will aim to extend his career beyond 2017.

"I'm feeling okay. My coach says my fitness is not exactly where it wants to be, starting out this season I had a problem with my ankles and it was a setback but not that bad. We're getting back on track and he's happy with the progress I'm making."

"Coach says I shouldn't say I want to retire just yet, I should focus on the year and see how I feel after the 2017 World Championships in London."

Bolt said he wants to be known as the greatest. "I met Pele today, for me it was like a dream come true. I always said I want to be the greatest, I want to be like Pele and Ali and all those guys. I want to be great. I want to be remembered as of the greatest that have ever done the sport."
