It was another big occasion and yet another world record for a Jamaican sprinter, Usain Bolt, on Sunday August 16th. At the athletics World Championships he broke the 100 metres sprint record again, taking his own time down to 9.58 seconds from 9.69 seconds, set a year ago at the Beijing Olympics. This is the most the record has fallen since electronic timing was first used in 1968. In the century or so since official records began a little more than a second has been shaved off the quickest time for the sprint, an improvement of 9%.
