Great Britain's track cycling success continued as Victoria Pendleton and the men's team pursuit both won gold on Friday evening at the velodrome.
The British quartet of Ed Clancy, Geraint Thomas, Peter Kennaugh and Steven Burke held off a challenge from Australia to win gold in the final of the men's team pursuit and smash the world record.
But the gold rush didn't stop there and Pendleton cruised to victory in the keirin final to become the most decorated British female track athlete of all time, with her gold moving Team GB up to third place in the medal table ahead of South Korea.
Pendleton secured Britain's third track cycling gold medal in less than 24 hours as she made a late dash for the line and managed to pip Guo Shang who took silver, while Lee Wai Sze of Hong Kong claimed bronze.
Pendleton was expected to be battling her bitter rival Anna Meares of Australia but she could only manage a fifth place finish.
The duo will go head-to-head again when Pendleton looks to defender her individual sprint title on Sunday.
"I can barely believe it right now," said Pendleton. "I think Jan [van Eijden] will have something to say about my tactics but he told me not to look for their race - when it's your moment, just go.
"I really wanted to show what I could do and it worked out well. The crowd have been fantastic, they really helped me today."
In qualifying for the final the British team pursuit four finished in a time of 3:52:49 as they beat Denmark as they showed their intent and laid down a major marker to the Australian quartet.
Australia's Jack Bobridge, Glenn O'Shea, Rohan Dennis and Michael Hepburn were the second fastest qualifiers but were more than three seconds behind Britain and they could do nothing to close the gap in the final as Great Britain took the world record in a time of 3:51:66.
