Usain Bolt: World Championships may not be my last event

The 30-year-old, who has eight Olympic and 11 World Championship gold medals to his name, revealed on Monday he had spoken to his coach Glen Mills about whether to end his last season following the showpiece event in London, but that they were undecided.

"We haven’t fully made up our mind on what we’re doing yet," revealed Bolt, who had previously said his final race would be the 4x100m relay final on August 12.

"I'm not worrying about that until the World Championships or at least getting close to it," he added.

Ahead of his 100m event in the IAAF event in Ostrava on Wednesday, Bolt, who did confirm that he would not compete in the 200m at the Olympic Stadium in London, added: ‘Right now, I'm just focused on getting through the season.

"I just like entertaining the crowd. I definitely want to try and enjoy every minute of it - it won't be the same sat in the stadium."

Bolt is the first man to have won the 100m and 200m in record times and the Jamaican also defended the pair of individual titles he won in Beijing 2008 at the following two Olympics.

"It's just been a great career. I've really enjoyed the ups and downs, all the experience I've gathered, all I've been through, the happiness and the sadness," he said.

"It's an emotional season."
