Team pursuit
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. 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. 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".
