Geraint Thomas is a Tour de France icon. The British rider might be best known for winning the general classification back in 2018, but his relationship with the legendary Grand Tour extends well beyond his summer in yellow.
The Welshman first lined up at the race’s London Grand Depart back in 2007 and has spent 14 of the last 18 summers clocking up the kilometres in France. In that time, he has played the role of domestique, Chris Froome’s climbing lieutenant, GC hope and old hand. As he makes his Grand Boucle swansong in his final season before retirement, he has the goal of a stage win as he attempts to go out on a high.
But even if he doesn’t manage it before the race enters the final stage’s Champs-Élysées circuit, Thomas has pulled together a Tour de France career that will be hard for anyone to match. So here are the numbers behind his near two decades of success.
- 7 remarkable numbers behind Tadej Pogačar's Tour de France success
- 6 surprising numbers behind Mathieu van der Poel’s Tour de France success

Geraint Thomas has clinched three Tour de France stage wins in his long and illustrious career.
His first came in 2017’s opening individual time trial in Dusseldorf. The following year, he secured back-to-back stage wins en route to the yellow jersey.
His first was a solo attack with 400m to go before stage 11’s La Rosière Espace San Bernardo’s finish line, which saw him ride into the general classification lead. He followed it up the next day by winning from a five-man sprint on Alpe d’Huez, becoming the first Brit to win on the iconic climb in the process.
7.445
Thomas has ridden a Pinarello Dogma for 12 of his 14 Tours de France, and his 2025 bike is built around the Dogma F launched at last year’s race.
We weighed his 2025 Pinarello Dogma ahead of the Grand Depart in Lille this year and the aero-focused build wasn't the lightest in the peloton, coming in at 7.445kg. But we expect a more weight-friendly version as the race and G hit the mountains.

The 2025 Tour de France is Geraint Thomas’ 14th start of Le Grand Boucle. The 39-year-old is the 108th edition’s oldest rider, while he was the youngest, aged 21 and 43 days, when he made his debut in 2007. Other riders to make their debut in 2007 included a certain Mark Cavendish.
14 (again)
Thomas has worn the yellow jersey for 14 days of racing. 10 of these came during his 2018 win, where he defended the jersey from stage 11 until the finish in Paris.
He also wore it for four days in 2017’s edition after winning the opening stage’s individual time trial, holding it until stage 5 when teammate Chris Froome took up the mantle. Thomas would retire on stage 9 with a broken collarbone – his only DNF at the Tour de France.
63
Thomas became the 63rd rider (if you discount the subsequently scratched-off editions) to win the Tour’s general classification in its 105th edition. He also became the third British rider to achieve the feat, following in the tyre tracks of Team Sky teammates Bradley Wiggins and Chris Froome.
68
Geraint Thomas has previously said his ideal race weight going into a Tour de France is a svelte 68kg.
The Welshman has also revealed he has an off-season weight of 75kg, meaning he has to shave almost one whole Pinarello Dogma F off his waistline to get race-ready.
470
Thomas shared on his and Luke Rowe’s Watts Occurring podcast that his best-ever 10-minute power is 470 watts. He also stated on a recent episode that he’d only be able to hold Tadej Pogacar’s 7.2W/kg 20 minutes power for seven minutes at his best, suggesting that around 490 watts is his seven-minute max.
46,485.2
If Thomas makes it to the finish in Paris, he will have cycled 46,485.2km during his 14 Tours de France. That’s more than one lap around the Earth’s equatorial circumference (40,075.017km). And to that we say, chapeau.
