As of 2014, the world record for fastest time in the 100-meter sprint is 9.58 seconds. The time was set by Jamaican Usain Bolt on Aug. 16, 2009, at the World Athletics Championship in Berlin.
Bolt twice eclipsed his own previous world records of 9.69 and 9.72 seconds, which he set on Aug.16, 2008, and May 31, 2008. Prior to Bolt, fellow Jamaican sprinter Asafa Powell held the world record at 9.74 seconds, a time he recorded on Sept. 9, 2007. Tim Montgomery was the last American to hold the top seat, though he was eventually stripped of the record after being found guilty of using performance-enhancing drugs.
