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 2012 Summer Olympics. In 2014, he won gold in the time trial at the road world championships, and founded the cycling team. Wiggins returned to the track at the 2014 Commonwealth Games, and in June 2015 he set a new hour record with a distance of . 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. Wiggins was appointed a CBE in 2009. Following his success in 2012, Wiggins was the subject of further honours and awards: the Vélo d'Or award for best rider of the year, the BBC Sports Personality of the Year Award and a knighthood as part of the 2013 New Year Honours. During his career and afterwards he faced a series of allegations that he exploited a loophole in cycling's anti-doping regulations to use a performance-enhancing drug, injections of the powerful corticosteroid, triamcinolone. He did not receive any bans or suspensions in relation to doping during his career. On 5 March 2018, the British House of Commons Committee for Digital, Culture, Media and Sport published their report called "Combatting doping in sport". They concluded inter alia that Team Sky had used the powerful banned corticosteroid triamcinolone in 2012 under TUE (Therapeutic Use Exemption) "to prepare Bradley Wiggins, and possibly other riders supporting him, for the Tour de France. The purpose of this was not to treat medical need, but to improve his power to weight ratio ahead of the race." The report concluded that "we believe that drugs were being used by Team Sky, within the World Anti-Doping Agency rules, to enhance the performance of riders, and not just to treat medical need." Early life and amateur career Wiggins was born on 28 April 1980 in Ghent, Flanders, Belgium, to an Australian father, Gary Wiggins, and a British mother, Linda. His father lived in Belgium as a professional cyclist. His father left the family when Wiggins was two.
