Sir Chris Hoy became the most successful British Olympian ever by winning his sixth gold medal in the men's Keirin.
The 36-year-old Scot moved level with Sir Steve Redgrave on Thursday by taking his first gold of the London 2012 Games in the team sprint and then went one ahead of the rowing legend by sealing the Keirin title in stunning style.
Germany's Maximilian Levy was second, while two bronze medals were awarded as Simon van Velthooven of New Zealand and Teun Mulder of Holland could not be separated by officials scrutinising the photo finish.
Hoy - who won one-kilometre time-trial gold in Athens eight years ago and triple Olympic gold four years later - said: "I'm 99.9% sure I won't be competing there in Rio. How can you top this? This is phenomenal.
"The 2014 Commonwealth Games in Glasgow? That's another question. If I can keep going to Glasgow that would be a dream ending for me but when you get to my age you can't look too far ahead, you have to focus on the here and now."
On his keirin victory, he said: "I'm in shock. You try to compose yourself and try to be able to take it all in but this is surreal.
"This is what I always wanted. I wanted to win gold in front of my home crowd. I can't express the feeling that I'm having right now, it's just unbelievable, it's the most amazing feeling.
Great Britain's Laura Trott claimed her second gold medal of London 2012 Games by storming to victory in the women's omnium.
The 20-year-old from Cheshunt - who also sealed team pursuit gold on Saturday - has now joined an elite group of British female athletes to have won double gold at a single Games, including Dame Kelly Holmes and swimmer Rebecca Adlington.
Trott won Track Cycling World Championships gold in each event and now has double Olympic gold too.
Sarah Hammer of the United States was second, with Annette Edmondson of Australia third.
Trott was two points behind Hammer entering the final discipline, the 500m time-trial, but claimed her third win from six disciplines to overhaul the deficit and win by a point.
She clocked 35.110 seconds, with Hammer finishing fourth in 35.900sec as a jubilant Trott triumphed on 18 points, with Hammer finishing with 19.
Trott said: "I came into today not feeling as good as yesterday, and I was losing my head a bit between events because they weren't going the way I wanted them to.
"To finish off with that 500m, I can't believe it. I'm really happy. Paul Manning, my coach, got me to peak right on time.
"I couldn't ask for much more from the coaching staff. They've helped me improve so much since the Worlds.
"It's all thanks to the coaches really, and my family and friends are here too, and the support of the crowd..."
Britain's Alistair Brownlee produced a dominant display of running to take the Olympic triathlon gold medal, with brother Jonny claiming bronze.
The older Brownlee brother cruised away from Spain's Javier Gomez on the final of the event's three disciplines to take a comfortable victory in Hyde Park.
Jonny was also present in the elite leading group heading into the run but slipped back before being forced to take a 15-second penalty for getting on his bike too early.
Jonny took his penalty on the third lap and came out still in third place, with French duo David Hauss and Laurent Vidal still some way behind.
Alistair gradually extended his gap and had time to collect a Union Flag before walking across the finish line, with Jonny finishing well clear in third but some way behind Gomez.
The Brownlees live and train together in the village of Bramhope near Leeds, and Alistair said: "I'm immensely proud that my brother could get a bronze.
"We made no secret of the fact we wanted to get both of us on the podium and that's not an easy thing to do considering Britain's never won a medal in triathlon.
"It shows the strength of training together, pushing each other on all the time and the relationship that we have."
Great Britain ended Germany's Olympic dominance in the dressage by taking the gold medal at Greenwich Park.
Hot on the heels of their counterparts triumphing in the showjumping, the trio of Carl Hester, Laura Bechtolsheimer and Charlotte Dujardin made history by claiming Britain's first Olympic dressage medal.
Germany had previously won every Olympic team gold in dressage since 1976, with the exception of the boycott year in 1980.
However they only just ended up with the silver this time around, holding off the determined challenge of the Netherlands to take second place on the podium.
"I was a bit more nervous today going in because I just wanted that gold medal," the 26-year-old Dujardin said. "I didn't want to let anyone down, and I like that test, so I knew I could do well in it.
"I had a flip I think in the one tempo change and my left pirouette didn't feel very good, but apart from that it felt pretty good.
"It's surreal because obviously I only started in January last year and I got a gold medal at the Europeans, and it was the ultimate dream to get here and ride here."
Great Britain's men are back in the Olympic hockey semi-finals for the first time since their gold-medal success of 1988.
The team earned the point they needed from their final match, drawing 1-1 with Spain on Tuesday night to book their place in the last four.
Team GB, who finished runners-up in their pool, will now face Group B winners the Netherlands for a place in the final.
Ashley Jackson scored his fifth goal in as many games to give his side a lead late in the first half and even though Pau Quemada converted a second-half set-piece allowing Spain to pile on some late pressure, Britain saw the game out to join their female counterparts in the semis.
The USA remain on track for a record fifth straight gold medal in women's basketball after routing Canada.
Welshman Fred Evans faced an anxious wait before finally discovering he had guaranteed a bronze medal.
South Korea, Brazil, the USA and Japan are all through to the women's volleyball semi-finals.
