He's already the fastest man in the world, but that's not enough for Usain Bolt. The six-time Olympic champion thinks he can break 19 seconds in the 200 metres. "I really want to run under 19 seconds," Bolt told Reuters during a training session in Kingston. "It's one of my major goals." Bolt is busy preparing for next year's Rio Olympics. He has held the record for both the 100m and 200m dash since 2009, at 9.58 seconds and 19.19 seconds respectively. "It will not be an easy task, but I personally feel I can do it," he added.
