British riders spoke of their passion and emotion after taking their tally of gold medals to four at the track cycling World Championships in Manchester.

Bradley Wiggins earned his second title in as many days as he drove home the British quartet in world-record time to win the team pursuit. Rebecca Romero, formerly a rowing world champion and Olympic silver medallist, stormed to victory in the women's individual pursuit. And Victoria Pendleton and Shanaze Reade successfully defended their title in the women's team sprint to keep the Brits on target to match the seven golds they won at last year's championships.

Wiggins was punching the air with half a lap left to go of the team pursuit final against Denmark. The time of 3min 56.322sec was almost a third of a second quicker than the previous record set by Australia in the Olympic final four years ago. "It's been quite emotional, the last couple of days," said the Londoner, who insisted the quartet of himself, Geraint Thomas, Ed Clancy and Paul Manning could go even quicker in Beijing this August.

"The big aim is always the Olympics. We had a couple of illnesses over the last six weeks so, yes, I do believe we can go faster."

Romero abandoned rowing two years ago and her win over defending champion Sarah Hammer, of the United States, was impressive for someone who had never been on a track bike until she was 26.

And she is already looking ahead to Beijing. "It will be tough following on from that, but it's only upwards now," she said.

Pendleton and Reade survived a technical fault at the start of their final to beat China's Jinjie Gong and Lulu Zheng. And Chris Hoy stayed on course for an individual gold by eliminating world and Olympic champion Theo Bos, of Holland, in the quarter-finals.
