Sir Chris Hoy and Joanna Rowsell gave the home fans another memorable night at London's Olympic Velodrome as both secured gold at the Track World Cup.

Four-time Olympic champion Hoy came around the outside on the final bend to edge out Germany's Rene Enders on the finish line and take keirin gold.

Rowsell then beat New Zealand's Alison Shanks to win the individual pursuit.

Victoria Pendleton had a less successful evening with fourth place in the individual sprint.

Ben Swift finished sixth in the men's omnium, winning the scratch race to move himself into medal contention before slipping back with an 11th-place ride in the kilo.

And Laura Trott put in an amazing display to win the elimination race and move to third in the women's omnium standings after three races.

The Londoner repeatedly escaped elimination with sprints to the line before out-pacing Canadian world champion Tara Whitten on the final lap.

"That wasn't the way I planned to ride," said Trott, who was part of the winning pursuit team on Friday. "I wanted to ride second wheel but I was just so tired from yesterday, so it was easier to just keep popping people. Day two's always my best day so bring it on."

Hoy, 35, had to settle for bronze in Friday's team sprint and looked like missing out again in the latter stages of the keirin, but the Scotsman's power came to the fore as he took the long route to victory down the home straight.

"I made it hard for myself there," Hoy told 91�ȱ� Sport. "With half a lap to go I wasn't sure I was going to make it but that crowd, when they see you're going to make that move, it's unbelievable. It's like an Olympics."

He added: "I have been deliberately trying to ride from the back, because if you win from the back and the front then you can deal with any situation.

"There's still a lot of work to be done between now and London but I'll always remember this event. Everybody's on their feet, full of energy, and we're feeding off that. You can almost see the other teams becoming a bit more defensive."

Rowsell made a strong start against Shanks in the pursuit final and held her form as the Kiwi cut the deficit midway through the race, with the Briton going away again in the closing stages to win in 3:32.364.

"I thought I would try to go out fast in order to get my nose out in front," said Rowsell. "I knew I could bring it back home in last kilo. I wound it up with four laps to go."

She added: "There's such a good team spirit, everyone is helping out each other. When I'm out on the track I feel I have the whole squad behind me. I knew it must have been goobecause of how loud it was."

Pendleton and Meares resumed a long-time rivalry in the individual sprint that has included the Briton's victory in the 2008 Olympic final and the Australian's win in last year's world final.

This time Pendleton found triple world champion Meares too strong, losing the deciding race of their semi-final when she gave the Australian a gap to attack and ultimately going down 2-1.

There were surprise results in the two medal races to follow, however, as China's Guo Shuang beat Meares 2-0 for gold, before Wai Sze Lee of Hong Kong saw off Pendleton 2-0 for bronze.

"I think meeting Anna Meares in the semis, we gave each other a bit of battering to be honest," said Pendleton.

"The racing was top quality and at this stage of the season it's quite hard to back up that sort of effort when you haven't really done the training for it."

Meares agreed about the effort taken to win her semi-final, saying: "I think both of us paid for it in the final. I'm really, really pleased with how I raced tonight. It was a hard-fought battle."

And the Australian was delighted to have got a taste of the track on which she will go for Olympic gold in August, adding: "It's the best experience I could have asked for.

"The velodrome is beautiful. I've never heard a crowd make so much noise in my life - it feels like 20,000 people, not 6,000, and is reflective of a country that loves a great sport, and a sport that I'm proud to be a part of."
