The women of Great Briton's Team Pursuit landed gold on Saturday evening, setting a new world record at the Olympic velodrome.
Joanna Rowsell, Dani King and Laura Trott finished in three minutes 14.051 seconds, outstripping Sarah Hammer, Dotsie Bausch and Jennie Reed of the United States who finished three minutes 19.727 seconds.
It was a stunning display by the host team, who powered through the final kilometre to take Olympic glory, increasing Team GB's medal haul. After three days of track cycling, GB has now won four out of a possible five golds on offer.
Canada's Tara Whitten, Gillian Carleton and Jasmin Glaesser took bronze, beating Annette Edmondson, Melissa Hoskins and Josephine Tomic of Australia.
The victory mirrored Friday's win by the men's team in the same discipline, when Ed Clancy, Geraint Thomas, Peter Kennaugh and Steven Burke posted a time of three minutes 51.659 seconds, beating Australia's Jack Bobridge, Glenn O'Shea, Rohan Dennis and Michael Hepburn.
Also on Friday, Victoria Pendleton made up for the bitter disappointment of being relegated from the team sprint and produced a storming finish to take the gold medal in the women's keirin.
Paul McCartney was in the crowd for the women's team pursuit victory. The former Beatle even sang along with Hey Jude, a song he wrote, when it was played over the sound system.
Speaking to the BBC, Trott said: "It's mad, I actually can't believe it. I feel dead emotional right now. It was my dream - it's been my dream since I was eight and we've just gone and done it."
King added: "We're like sisters and I couldn't have done it without them. They were absolutely incredible. I can't believe we've done it. It's absolutely amazing."
