On the track, he has won three World Championships ([[2007 UCI Track Cycling World Championships|2007]], [[2008 UCI Track Cycling World Championships|2008]], and [[2012 UCI Track Cycling World Championships|2012]]), and two Olympic gold medals ([[Cycling at the 2008 Summer Olympics – Men's team pursuit|2008]] and [[Cycling at the 2012 Summer Olympics – Men's team pursuit|2012]]), while on the road he won the [[2018 Tour de France]] becoming the first [[Welsh people|Welshman]] and third British rider to win it.<ref>{{Cite news |title=Tour de France: Geraint Thomas becomes first Welshman to win – CBBC Newsround |url=https://www.bbc.co.uk/newsround/44991134 |access-date=2022-06-20}}</ref><ref>{{Cite web |last=Sands |first=Katie |date=2022-06-19 |title=Wales' Geraint Thomas becomes first Brit to win Tour de Suisse |url=https://www.walesonline.co.uk/sport/uk-sport-news/wales-geraint-thomas-becomes-first-24267214 |access-date=2022-06-20 |website=WalesOnline}}</ref>

His early successes were in track cycling, in which he was a specialist in the [[team pursuit]]. He won three World Championships and was Olympic gold medallist twice, in [[Cycling at the 2008 Summer Olympics – Men's team pursuit|2008]] and [[Cycling at the 2012 Summer Olympics – Men's team pursuit|2012]]. Thomas had an early win on the road at the 2004 [[Paris–Roubaix Juniors]] and later had a senior victory at the 2010 [[British National Road Race Championships]]. Leaving track cycling to focus solely on the road, he subsequently found success in both one-day/[[classic (cycling)|classic]] races such as the [[Cycling at the 2014 Commonwealth Games – Men's road race|2014 Commonwealth Games road race]] and the [[2015 E3 Harelbeke]], and in one week stage races, most notably at the [[2016 Paris–Nice]], the [[2017 Tour of the Alps]], the [[2018 Critérium du Dauphiné]], the [[2021 Tour de Romandie]] and the [[2022 Tour de Suisse]].

In cycling's [[Grand Tour (cycling)|grand tour]]s, Thomas was initially a lead [[domestique]] to [[Chris Froome]] in his victories. He won the first stage of the [[2017 Tour de France]], an [[individual time trial]], to become the first Welshman to wear the Tour's [[yellow jersey]]. He later crashed in that race, as well as in the [[2017 Giro d'Italia]]. Thomas became the first Welshman to win the [[Tour de France]] when he won the race in [[2018 Tour de France|2018]]. He gained the yellow jersey by winning stage 11, extended his lead by winning stage 12, and retained the lead for the remainder of the race. In the same year he won the [[2018 BBC Sports Personality of the Year Award|BBC Sports Personality of the Year Award]], becoming the first Welshman to win the award since Ryan Giggs in 2009.<ref>{{Cite news |title=Thomas voted Sports Personality 2018 |publisher=BBC Sport |url=https://www.bbc.com/sport/sports-personality/46566121 |access-date=2022-07-24}}</ref> In 2019, he confirmed his Grand Tour pedigree when he reached the podium again, having finished runner-up in the Tour de France behind {{UCI team code|INS|2019b}} teammate [[Egan Bernal]]. In 2022, Thomas became the first Welshman to win the Tour de Suisse and later that year recorded another podium finish at the [[2022 Tour de France|Tour de France]], placing third.<ref>{{Cite web |last=Sands |first=Katie |date=2022-06-19 |title=Wales' Geraint Thomas becomes first Brit to win Tour de Suisse |url=https://www.walesonline.co.uk/sport/uk-sport-news/wales-geraint-thomas-becomes-first-24267214 |access-date=2022-07-24 |website=WalesOnline}}</ref><ref>{{Cite web |author1=Chris Marshall-Bell |date=2022-07-24 |title=Geraint Thomas proves doubters wrong with another Tour de France podium: 'Deep down I knew I could still be good' |url=https://www.cyclingweekly.com/racing/geraint-thomas-proves-doubters-wrong-with-another-tour-de-france-podium-deep-down-i-knew-i-could-still-be-good |access-date=2022-07-24 |website=cyclingweekly.com}}</ref> A fourth grand tour podium, and a first outside of the Tour de France, was won in 2023 as Thomas took second place in the [[2023 Giro d'Italia|Giro d'Italia]], losing the race lead to [[Primož Roglič]] on the penultimate day. A fifth grand tour podium was secured in the [[2024 Giro d'Italia|following Giro]], less than half a minute behind runner up [[Daniel Martínez (cyclist)|Danny Martinez]], but almost ten minutes behind winner [[Tadej Pogačar|Tadej Pogacar]]. After the race, Thomas suggested he would no longer race for general classification at the grand tours<ref>{{cite news |url=https://www.nbcsports.com/olympic/news/primoz-roglic-giro-ditalia |title=Primoz Roglic wins Giro d'Italia over Geraint Thomas |work=[[NBC Sports]] |publisher=[[NBC]] |date=28 May 2023 |accessdate=1 July 2023}}</ref>

Notable for his all-round ability and adaptability rather than mastery of one specialism, Thomas has been competitive in individual time-trials, on the cobbles, in the Spring classics and in the mountains of Grand Tours, where he was the first rider in the history of the Tour de France to win at [[Alpe d'Huez]] while in yellow.

==Early life and amateur career==
Born in [[Cardiff]], Wales, Thomas attended [[Whitchurch High School]].<ref>{{cite web |url=http://www.geraintthomas.com/about/ |title=About Geraint |publisher=Geraint Thomas's website |year=2015 |access-date=25 July 2015}}</ref> He began cycling with the Maindy Flyers Cycling Club at [[Maindy Centre|Maindy Stadium]] at the age of 10,<ref>{{cite web |url=http://autobus.cyclingnews.com/road/2007/tour07/?id=/riders/2007/interviews/tour_geraint_thomas_pre07 |title=An interview with Geraint Thomas |publisher=cyclingnews.com |date=5 July 2007}}</ref> where he rode with future Team Sky teammate [[Luke Rowe]], before going on to ride for other local clubs, Cycling Club Cardiff and Cardiff Just in Front.

==Professional career==

===2005–2006: early years===
Thomas became a member of [[British Cycling]]'s Olympic Academy. He won the Carwyn James Junior Award at the [[BBC Wales Sports Personality of the Year]] ceremony. Thomas competed at World Cup events around the world, and was training in [[Sydney]], Australia, in February 2005 when he crashed after the rider in front of him hit a piece of metal in the road which was flicked up into Thomas's wheel. He suffered internal bleeding after the piece of metal entered his body during the fall, rupturing his [[spleen]] which subsequently had to be removed.<ref>{{cite web |url=http://www.britishcycling.org.uk/web/site/BC/tra/EventReports2005/20050327_Worlds_Thomas.asp |title=Geraint Thomas Recovering from Aussie Crash |author=Larry Hickmott |publisher=British Cycling |date=27 March 2005 |url-status=dead |archive-url=https://web.archive.org/web/20081203161007/http://www.britishcycling.org.uk/web/site/BC/tra/EventReports2005/20050327_Worlds_Thomas.asp |archive-date=3 December 2008}}</ref><ref>{{cite news |url=http://news.bbc.co.uk/sport1/hi/other_sports/cycling/4276183.stm |title=Thomas in hospital after crashing |publisher=BBC Sport |access-date=29 January 2013 |date=18 February 2005}}</ref>

He rode most of his races of 2006 for {{UCI team code|RCS|2006}}, but towards the end of 2006 joined {{UCI team code|SDV|2006}} as a stagiaire. He also rode a few races, such as the [[Tour of Britain]], for the Great Britain squad.<ref>{{Cite web |title=A look back at Geraint Thomas's OVO Energy Tour of Britain career |url=https://www.tourofbritain.co.uk/a-look-back-at-geraint-thomass-ovo-energy-tour-of-britain-career/ |access-date=2022-01-19 |website=Tour of Britain}}</ref>

===2007: Tour de France debut===

Thomas made his [[Tour de France]] debut at the [[2007 Tour de France|2007 race]] as the youngest rider in the race as {{UCI team code|BAR|2007}} picked up one of the three wildcard spots allocated for the race. He became the first Welsh rider to compete in the race since [[Colin Lewis]] in 1967.<ref>{{cite news |url=http://news.bbc.co.uk/sport1/hi/other_sports/cycling/7129763.stm |title=Thomas backed for Beijing glory |publisher=BBC Sport |access-date=29 January 2013 |date=5 December 2007}}</ref> Thomas received great support from Welsh fans at the opening of the race, with several following the entire race.<ref>{{cite web |url=http://www.britishcycling.org.uk/web/site/WCU/lei/News2007/20070717_Maindy_Tour_Trip.asp |title=Maindy Flyers 'On Tour'! |author=Ian Jenkins |publisher=Welsh Cycling |access-date=29 January 2013 |date=17 July 2007 |url-status=dead |archive-url=https://web.archive.org/web/20081123023153/http://www.britishcycling.org.uk/web/site/WCU/lei/News2007/20070717_Maindy_Tour_Trip.asp |archive-date=23 November 2008}}</ref> He completed his first Tour de France, finishing 140th of 141 finishers.<ref>{{cite web |url=http://www.letour.fr/2007/TDF/LIVE/us/2000/classement/index.html |title=2007 Tour de France, Overall Standing |publisher=Le Tour de France |access-date=29 January 2013 |date=29 July 2007}}</ref>

He was nominated for the BBC Wales Sports Personality of the Year award in 2007.

===2008: Olympic gold===
Thomas did not compete in the [[2008 Tour de France|Tour de France]], instead, he rode the [[2008 Giro d'Italia|Giro d'Italia]] earlier in the season before returning to Britain to concentrate on preparations for the [[2008 Summer Olympics|Summer Olympics]] in Beijing.<ref>{{cite web |url=http://www.cyclingweekly.co.uk/olympics/The_Big_Interview_Geraint_Thomas_article_258329.html |archive-url=https://archive.today/20110809130905/http://www.cyclingweekly.co.uk/olympics/The_Big_Interview_Geraint_Thomas_article_258329.html |url-status=dead |archive-date=9 August 2011 |title=THE BIG INTERVIEW: GERAINT THOMAS |publisher=Cycling Weekly |access-date=29 January 2013 |date=11 June 2008}}</ref> On discovering that the flags of non-participating nations would not be allowed at the Games, Thomas said: "It would be great to do a lap of honour draped in the Welsh flag if I win a gold medal, and I'm very disappointed if this rule means that would not be possible."<ref>{{cite news |url=https://www.telegraph.co.uk/sport/othersports/olympics/2505509/Beijing-Olympics-Flags-showing-Cross-of-St-George-Saltire-or-Welsh-dragon-banned.html |archive-url=https://web.archive.org/web/20080806113723/http://www.telegraph.co.uk/sport/othersports/olympics/2505509/Beijing-Olympics-Flags-showing-Cross-of-St-George-Saltire-or-Welsh-dragon-banned.html |url-status=dead |archive-date=6 August 2008 |title=Beijing Olympics: Flags showing Cross of St George, Saltire or Welsh dragon banned |author=Gordon Rayner |work=The Telegraph |publisher=Telegraph Media Group Limited |date=6 August 2008 |location=London}}</ref><ref>{{cite web |url=http://www.walesonline.co.uk/news/politics-news/2008/08/05/olympic-officials-ban-welsh-athletes-from-flying-national-flag-91466-21468144/ |title=Olympic officials ban Welsh athletes from flying national flag |author=Martin Shipton |publisher=South Wales Echo |access-date=29 January 2013 |date=5 August 2008}}</ref>

On 17 August, Thomas was a member of the Olympic team pursuit squad which broke the world record in the heats with a time of 3:55.202, beating their Russian opponents comfortably to go through to the final ride-off for silver and gold.<ref name="wr-1">{{cite news |url=http://news.bbc.co.uk/sport1/hi/olympics/cycling/7566164.stm |title=GB pursuit team set world record |publisher=BBC Sport |access-date=29 January 2013 |date=17 August 2008}}</ref> The following day, on their way to winning the gold medal, the British Team pursuit broke their own world record in a time of 3:53.314, beating their Danish competitors by 6.7 seconds.<ref name="wr-2">{{cite news |url=http://news.bbc.co.uk/sport1/hi/olympics/cycling/7567845.stm |title=GB storm to gold in team pursuit |publisher=BBC Sport |access-date=29 January 2013 |date=18 August 2008}}</ref> Thomas had been a possible contender in the individual pursuit, but opted not to ride both events as he did not want to compromise the efforts of his team. He had also been considered to compete in the Madison with [[Bradley Wiggins]] but it was [[Mark Cavendish]] who was selected to do so; [[Chris Boardman]] stated that "Geraint keeps surpassing people's expectations".<ref>{{cite news |url=http://news.bbc.co.uk/sport1/hi/olympics/cycling/7524460.stm |title=Thomas & Cavendish fight for spot |publisher=BBC Sport |access-date=29 January 2013 |date=25 July 2008}}</ref>

Following the disqualification of fellow {{UCI team code|BAR|2008}} teammate, [[Moisés Dueñas]], from the Tour de France, Thomas expressed his strong anti-doping opinions on his blog on the BBC [[606 (radio show)|6-0-6]] website: "...if someone is fraudulent in a business, wouldn't they be facing a prison term? I don't see how riders taking drugs to win races and lying to their teams is any different.

In December, he was appointed [[Order of the British Empire#Current classes|Member of the Order of the British Empire]] (MBE) in the 2009 [[New Year Honours]].<ref>{{London Gazette|issue=58929 |date=31 December 2008 |page=23 |supp=y}}</ref>

===2009===
[[File:Tour of Britain 2009 Stage 2 Geraint Thomas AB.JPG|thumb|upright|Thomas at the [[2009 Tour of Britain]]]]
Thomas suffered a bad start to his 2009 season when he broke his pelvis and fractured his nose in a fall; he crashed into a safety barrier having misjudged a turn in the time trial stage of the [[2009 Tirreno–Adriatico|Tirreno–Adriatico]] in [[Macerata]], Italy. The crash came shortly after an {{convert|8|km|abbr=on}} time check showed he was second fastest on the road. Although he was able to return to his team hotel from hospital the same day, a period of 20 days complete rest was required before he would be able to resume training.<ref>{{cite web |url=http://autobus.cyclingnews.com/news.php?id=news/2009/mar09/mar16news2&from=rss |title=Latest Cycling News: Broken bones for Thomas |work=Cycling News |date=16 March 2009}}</ref><ref>{{cite web |url=http://www.dailypeloton.com/displayarticle.asp?pk=14359 |title=44th Tirreno–Adriatico&nbsp;– Stage 4 & 5 Comnments & Photos |publisher=Daily Peloton |date=15 March 2009 |url-status=dead |archive-url=https://web.archive.org/web/20120223151821/http://www.dailypeloton.com/displayarticle.asp?pk=14359 |archive-date=23 February 2012}}</ref>

===2010: move to Team Sky===
Thomas began 2010 as part of the [[team time trial]] winning team for Sky at the [[2010 Tour of Qatar|Tour of Qatar]]. After competing in the [[Classic cycle races|classics]], he impressed at the [[2010 Critérium du Dauphiné|Critérium du Dauphiné]], finishing in the top ten in each of the opening four stages. As a result of these finishes, he was the leader in [[green jersey]] competition for stages two, four and six. He finished fifth in the green jersey competition overall, and twenty-first in the general classification.

Thomas beat teammate [[Peter Kennaugh]] to win the 2010 [[British National Road Race Championships]]. His good form continued into the [[2010 Tour de France|Tour de France]], in which he finished fifth in the prologue, a second behind the highest-placed overall contender [[Lance Armstrong]]. He then finished second on stage three, a stage that was marred by numerous crashes and splits in the [[peloton]], which Thomas managed to avoid.<ref>{{cite news |first=Juliet |last=Macur |url=https://www.nytimes.com/2010/07/07/sports/cycling/07tour.html |title=A Rocky Ride for Armstrong on Another Day of Crashes |work=[[The New York Times]] |date=6 July 2010 |accessdate=25 June 2022}}</ref> This led to him leading the [[Young rider classification in the Tour de France|young rider classification]] after stage three. He finished 67th overall in the Tour, and ninth in the young rider classification.

Thomas had been due to travel to [[Delhi]], India, in September to compete in the [[2010 Commonwealth Games|Commonwealth Games]], but pulled out, as did several other cyclists, due to health concerns. [[Dengue fever]] was one specific concern cited. Illness was especially a risk for Thomas following the removal of his [[spleen]] in 2005. Following the decision, Thomas said "It's a massive disappointment, I only get to ride for Wales once every four years, but that's the decision I had to make."<ref>{{cite news |url=http://news.bbc.co.uk/sport1/hi/other_sports/cycling/8825573.stm |title=Geraint Thomas pulls out of Commonwealth Games in Delhi |publisher=BBC Sport |date=24 September 2010 |access-date=15 July 2011}}</ref>
