Bolt quashes retirement talk

Usain Bolt says he will definitely compete in the 2016 Olympic Games in Rio.

Speculation has been rife since the London Games that the Olympic 100 metres and 200m champion could quit athletics before Rio.

However, his hunger for success appears to be showing no signs of abating.

"Yes definitely I will be there (in Rio), as long as I'm fit and I'm ready," Bolt said. "It'll be a little bit harder but I'm looking forward to it."
