Jamaican sprint superstar Usain Bolt has claimed that when he is at his best then it's definitely almost impossible to beat him, insisting that he wants to break his own 200-metre world record and do it by running under 19 seconds.
Bolt set the record of 19.19 seconds in 2009, and also set the 100 record of 9.58 in the same year. He said that breaking his own 200-metre record is one of his biggest goals, adding that it is actually to run under 19 seconds.
The six-time Olympic gold-medalist said that he thinks this season it would be hard to do, but added that they key thing is trying to stay injury free so he can go into the Olympic season in the best shape that he can be, Sport24 reported.
Bolt, who is in Rio to run an exhibition race over the weekend, also said that when he is in great shape, he worries about nobody because he knows that when he is at his best it's definitely almost impossible to beat him.
Bolt reiterated that Rio would be his last Olympics, but not his last season, and revealed that he would retire after the 2017 world championships in London.
