Tour winner Geraint Thomas - a career in pictures

From the Tour de France to Olympic medals and World Championships, Geraint Thomas has won many of cycling's biggest prizes during a glittering 19-year career.

As he begins his final race as a professional – the Tour of Britain, which finishes in Cardiff on Sunday, 7 September – here is a look back at some of the 39-year-old Welshman's career in pictures.

Geraint Thomas had a keen interest in cycling from a young age. Here he is - second from the left - after he joined Maindy Flyers in 1995

His former coach Debbie Wharton says he quickly improved as a cyclist when he was 14 years old

At 21, Thomas was the youngest cyclist at the 2007 Tour de France as he competed in the race for the first time. Here he is having medical tests with his team Barlowood a couple of days before the race

Thomas had a lot of success on the track at the start of his career - including a gold medal at the 2008 Olympic Games in the team pursuit with Paul Manning, Ed Clancy and Bradley Wiggins. He won a gold medal at the 2012 Olympics as well

As well as an Olympic gold medal in 2012, he was part of the winning team at the World Championships in Australia in the same year. Here he is in a qualifying race in London with the rest of his team - Steven Burke, Ed Clancy and Peter Kennaugh

2018 was a monumental year in Thomas' career. Here he is with wife Sara at the end of the 20th stage of the Tour de France, when it became obvious that the Welshman was going to win the race

Thomas was able to celebrate with Team Sky team-mate Chris Froome during the last stage of the 2018 Tour de France, as by tradition the overall leader is not challenged on the final ride into Paris

Having won the Tour de France in 2018, he finished second in 2019 and third in 2022, here leading the peleton during his final Tour appearance in 2025
