Triathlon drug testing

The World Triathlon Corporation has announced that American Tim Marr has committed an anti-doping rule violation.

USA Triathlon says that drug testing at the USA Triathlon Age Group National Championship in Tuscaloosa, Ala. was welcomed by participating athletes and that all results came back negative.

Three-time Ironman world champion Chrissie Wellington has posted her drug test history dating back to 2008 on her website and says she will update it regularly in an attempt to call attention to the need for stringent drug testing and to "provide proof that athletes can achieve great things without the need to cheat."
