Thomas claimed Olympic team pursuit gold on the track at both Beijing 2008 and London 2012 before going on to win the Tour de France in 2018, becoming the third Briton and only Welshman to win road cycling’s biggest race.
British Cycling performance director Stephen Park added: “On behalf of British Cycling, I would like to congratulate Geraint on a stellar career, one that has shown what is possible within such a gruelling and captivating sport for those who have the grit and determination to succeed at the highest level.
He was also part of the Great Britain team that helped Mark Cavendish become road race world champion in 2011, while his track exploits included three team pursuit world championship golds.
He won Commonwealth gold for Wales in the road race in 2014, was British champion in both the road race and time trial and finished on the podium twice at the Giro d’Italia.
Thomas played a supporting role in all four of Chris Froome’s Tour de France successes between 2013 and 2017 and finished second to team-mate Egan Bernal in the 2019 edition, before claiming a third podium place in 2022.
