Justin Gatlin is an American sprinter, who is an Olympic gold medalist in the 100 meters. His 100 m personal best is 9.77 seconds, and he is a twice World indoor champion in the 60 meters dash. In 2006, he began to serve a four-year ban from track and field for testing positive for a banned substance, with this sanction erasing his then-world-record time of 9.77 in the 100 m. Gatlin began competing again in August 2010, soon after his eligibility was reinstated. 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-m final, earning him a bronze medal. His performance at the 2012 Olympic 100 meter final contributed to the fastest 100 m race ever, which saw three men run under the 9.80-second barrier. Gatlin became the world leader of 2014 in the 200 meters on 18 July, when he won his race in 19.68 seconds at the Diamond League event in Monaco.
