British cyclist and London 2012 poster girl Victoria Pendleton has won gold in the women's keirin.

The 31-year-old washed away the disappointment of her disqualification yesterday in the team sprint by taking the top spot with a flawless performance in her least-favorite event.

She held off Guo Shuang of China, who claimed the silver medal, while Lee Wai Sze of Hong Kong took bronze.

Pendleton, who won the individual sprint in Beijing four years ago, will retire after the London Games and was determined to go out in style.

After the race she said: "Thank you so much to everyone who's helped me get here,

"The crowd have been fantastic and it really helped me today. My legs were good from last night and I still wanted to really show what I've got and it worked out okay, I guess."

Pendleton's win came just moments after Ed Clancy, Geraint Thomas, Peter Kennaugh and Steven Burke won the team pursuit title in a world record time, giving Britain its third gold medal in two days of competition on the super fast track.
