David Zabriskie

David Zabriskie is a retired American professional road racer who competed from 1999 to 2013 and was at his best against the clock. His career highlights include stage wins in all three Grand Tours and seven United States national time trial championships. Known for a quirky personality, he sang before stages and posted interviews with fellow riders on his website. In 2005 he became the third American to wear the yellow jersey at the Tour de France after winning the prologue, but his later admission of drug use led to the stage win and the jersey being taken away. In 2012, as a member of Garmin-Sharp, he accepted a six-month ban for doping during his time with the US Postal team, and his results from 2003 to 2006 were stripped.
