Justin Gatlin is an American sprinter who won the gold medal in the 2004 Summer Olympics 100-meter race in 9.85s and his personal best in 100 meters remains 9.74 seconds. An exceptional athlete, he turned pro in his teens along with a well-paid endorsement contract from American multinational corporation, Nike Inc. He became World indoor champion in the 60-meter dash twice. However he has also been in controversy for wrong reasons. He faced a two year ban from Athletics in 2001after testing positive for a banned substance. Again in 2006 a four year ban was imposed on him from field and track when he was once more tested positive for a banned substance. This time his then world record time of 9.77s set in May 2006 in 100m was also annulled. Making a comeback in international track and field in August 2010 he ran a time of 9.80s at the United States Olympic Trials in June 2012 - the fastest time attained any male athlete above thirty years of age. On July 18, 2014, his 19.68s in 200m at the ‘IAAF Diamond League’ event in Monaco made him the world champion in 2014.
