Back in 2009 22-year-old Usain Bolt, who was only passed fit after a car crash which required minor surgery on his foot just over a fortnight ago, was given a bye into the final.
But he did not disappoint and the breakdown of times in his sprint were staggering.
He covered the first 100m in 9.90, which although well short of his record-breaking 9.69 in Beijing, was still impressive on a very damp temporary track constructed in the city center.
Even better was his speed over what is termed “the flying 100” — from 50-150m — which he covered in just 8.72 seconds.
It all added up to a run which eclipsed the previous best of 14.75 by American Tyson Gay, whose time was recorded during a 200m race and not a straight 150m sprint.
“It is one more to the tally,” Bolt told reporters when told of his world-best time. “I thought I would just go out there and run a good time. I am not in the best shape and I still have a lot of work to do but I am getting there,” he added.
