COMING UP:Share Opener Variant 1



>> The fastest man who has ever lived is going to try to slow down. Jamaican sprinter Usain Bolt set to hangup his running spikes after the World Athletics Championships which start in London on Friday. Right now though, there's little time for reminiscing. Bolt means business at this year's worlds.
>> Yeah, I'm ready, I'm always ready.>> He laughed off the idea of losing the 100 meter at a press conference this week. And who would question the man with 11 of the titles already under his belt? Add to that the tally of Olympic golds in Beijing, London, and Rio, all of which make him the greatest sprinter in history.
Bolt's swansong will begin on Friday at the London Stadium, built when the city hosted the Olympics in 2012. If he makes it through the heats, the finale of his nearly decade-long career will be on Saturday with the 100 meter final. And quite a crowd due to turn out for the seminal moment.
>> 1, 2, 3.>> The championships are expected to have the highest attendance figures since they began.
