Olympic Cycling:Chris Hoy won the sixth Olympic gold medal of his career to become Britain's most successful Olympian of all time today, shortly after Laura Trott won the women's omnium to increase the hosts' remarkable form in the velodrome.
Hoy's victory in the keirin event took him past Steve Redgrave in terms of gold medals. Redgrave won five golds in successive Games between 1984 and 2000.
It was Hoy's second gold of the London Games - he was also victorious in the team sprint - and meant GB ended the track cycling programme with champions in seven of the 10 events.
The 36-year-old, who also won a gold in Athens in 2004 and three in Beijing four years ago, stormed to the front in the final with two laps to go.
It momentarily looked like he might have gone too early when he was challenged on the final lap by German Maximilian Levy, who briefly hit the front in the back straight, but the Scot responded on the last bend to ensure he crossed the line first.
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.
Trott'swin thrilled the home crowd.
Going into the last of six races in the multi-discipline event - the 500m time trial - she needed to finish three places higher than American rival Sarah Hammer, the pair having been neck and neck throughout the two-day competition.
Trott, the reigning world champion, duly posted the fastest time, with Hammer, on the other side of the track, only fourth.
It left Trott, who won three of the six disciplines, the winner by a single point in the overall standings.
The 20-year-old from Cheshunt won team pursuit gold on Saturday but has now won an individual title to join an elite club of British females to have won double gold at a single Games, including Dame Kelly Holmes and swimmer Rebecca Adlington.
Trott said: "I can't believe this is happening to me, I really can't. 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."
Annette Edmondson of Australia took the bronze medal after finishing just behind Trott in the time trial.
The final race of Victoria Pendleton'scareer ended in disappointment as she was beaten in the Olympic sprint final.
Following a string of impressive petrformances throughout the week in the velodrome, including a gold medal in the keirin, Pendleton went in as favourite against long-time rival Anna Meares. However, she was beaten 2-0 by the Australian and had to settle for the silver medal.
Pendleton actually crossed the line first - by a matter of centimetres - in the opening race of the best-of-three final but was demoted afterwards for deviating from her sprinting line.
Pendleton had to respond in the second bout to force a decider and Meares was in front first, watching her opponent. Meares came to a near halt at the end of the first of three laps, forcing Pendleton to the front.
The Australian then rounded Pendleton on the outside and the Briton could not respond as Meares celebrated before the line by punching the air.
The British star, who won sprint gold in Beijing four years ago, now heads into retirement.
Pendleton told the BBC: "I'm just so relieved right now. I've been a bit overwhelmed with emotion. I would have loved to have won on my final race but I'm just so glad that's it all done and I can move on."
She also paid tribute to Meares, who has been her main adversary throughout her career, and it was perhaps fitting that she bowed out against the Australian.
"I'm glad that it got to that stage," Pendleton said. "I think she's the best rider in the field and it's the way that it should have been. Everything turned out right with Anna and myself in the final. She's a fantastic competitor, we've met many a time, and I wish her all the best but I'm very glad to be saying that's the last time I have to go through that."
China's Guo Shuang won bronze with a 2-0 defeat of Kristina Vogel of Germany.
