Sir Bradley Marc Wiggins (born 28 April 1980) is a British former professional road and track racing cyclist, who competed professionally between 2001 and 2016. Nicknamed "Wiggo", he began his cycling career on the track, but made the transition to road cycling and is one of the few cyclists in the modern era to gain significant elite level success in both those forms of professional cycling.

He competed on the track from the early part of his career until 2008. Between 2000 and 2008 he won ten medals at the track world championships, of which six were gold: three in the individual pursuit, two in the team pursuit and one in the madison. His first Olympic medal was a silver in the team pursuit in Sydney 2000, before winning three medals including the gold in the individual pursuit at the Athens 2004, and two golds in the individual and team pursuit at the Beijing 2008.

In 2012, Wiggins won the Paris–Nice, the Tour de Romandie, the Critérium du Dauphiné, and became the first British cyclist to win the Tour de France and the time trial at the Olympic Games. In 2016, he won a further world championship in the madison, and gold in the team pursuit at the Olympics, his fifth successive medal winning appearance at the Games. He retired from all forms of professional cycling on 28 December 2016.
