Bradley Wiggins became Britain's most-decorated Olympian on Wednesday, winning the cycling time trial gold for his seventh medal overall.
Wiggins overhauled legendary rower Steve Redgrave's total of six medals as he beat out stiff competition from German world champion Tony Martin to seal victory in 50 minutes, 39.54 seconds.
"It was really incredible. To win an Olympic gold in your home city," he said.
"When you win in the velodrome, there are three or four thousand people cheering. Here, around the streets of London, the noise is just amazing. I don't think anything will top that."
The winning margin over Martin was 44 seconds.
Britain's Chris Froome grabbed the bronze, clocking 51 minutes 47 seconds.
Defending Olympic champion Fabian Cancellara of Switzerland was unable to challenge for the podium, finishing fourth.
Wiggins had done most of the damage by the 29km stage, when he had a 22-second advantage over Martin.
It is turning into a dream summer for the 32-year-old Wiggins, who last month became the first Briton to win the Tour de France yellow jersey.
It is his fourth career Olympic gold, after taking the individual pursuit title in 2004 and 2008, and the team pursuit in Beijing.
The other medals are one silver, in the 2004 team pursuit, and two bronze, in the 2004 madison and 2000 team pursuit.
Despite breaking Redgrave's record, Wiggins said the gold medals were the only ones that really mattered to him.
"It's not so important that you have seven medals if they're not the right colour. The main number is four," he said.
He vowed he would push on for more medals at the 2016 Olympics in Rio de Janeiro.
"I've got to carry on to Rio," he said.
Earlier Wednesday, American rider Kristin Armstrong charged to victory in the women’s time trial.
Silver went to Germany’s Judith Arndt 15 seconds back, while Russian rider Olga Zabelinskaya claimed her second bronze of the Games after also coming third in Sunday's road race.
