David Millar is a Scottish road racing cyclist riding for Garmin-Sharp. He has won five stages of the Tour de France, two of the Vuelta a España and one Stage of the Giro d'Italia. He was the British national road champion and the national time trial champion, both in 2007. He is the only British rider to have worn all Tour de France jerseys and one of five to have worn the yellow jersey. He was also the first British rider ever to have worn the leader's jersey in all three Grand Tours. He was banned for two years in 2004 after admitting taking banned performance-enhancing drugs, but four years after his return he won the silver medal at the World Time Trial Championships. In June 2011 he published his autobiography titled Racing Through the Dark, which Richard Williams in The Guardian wrote was "one of the great first-person accounts of sporting experience".
