Gatlin becomes a testing titan

Justin Gatlin, the 2004 Olympic 100m gold medalist who was suspended from 2006-10 after failing a second drugs test but is currently dominating the world of sprinting, has been tested 59 times by the US anti-doping agency since his return.

According to USADA figures released on Wednesday, Gatlin has already been tested nine times this season. In 2014, there were 15 tests, 14 in 2013, 13 in 2012 and eight in 2011.

The tests were conducted in and out of competition.
