Justin Gatlin (born February 10, 1982) is an American sprinter who is an Olympic gold medalist with a 100 m personal best of 9.79 seconds, and a two-time World indoor champion in the 60-meter dash. In 2006, he began to serve a four-year ban from track and field for testing positive for a banned substance, the ban of which erased his then world-record time of 9.77 in the 100 meters. Gatlin began competing again in August 2010, 4 years after his ban. In June 2012 at the US Olympic trials, Gatlin ran a time of 9.80 which was the fastest ever time for a man over the age of 30. At the London 2012 Olympics, Gatlin ran a time of 9.79 in the 100 meter final, earning him a bronze medal. His performance at the 2012 Olympic 100 meter final contributed to the fastest 100 meter race ever which saw three men run under the 9.80 second barrier.
