New Zealand's cyclist Sarah Ulmer regained her world record in the qualifying of women's individual pursuit event while British cyclist Bradley Wiggins and the German team took the gold medals produced in the Olympic Velodrom on Saturday.

With a time of three minutes and 26.400 seconds, Ulmer, 28, who made Olympic debut in Athens, beat the world record of 3:29.945 set by Australian Katie Mactier minutes ago.

Just before Ulmer's race, Mactier broke the previous world mark of 3:30.604 set by the New Zealander at World Championships this May.

While in the men's individual pursuit final, British rider Bradley Wiggins lived up to the expectation by winning the gold in four minutes and 16.304 seconds, beating Australian Brad McGee of Australia to the second at 4:20.436.

Wiggins led from the start and powered away in the second half of the race to clinch his Olympic gold, a second one for Britain at the track cycling after Chris Hoy's success in the 1km time trial Friday.

The British rider, who was placed first at World Championships in 2003, created the new Olympic record of 4:15.165 at the qualifying of the discipline on Friday, seeing off the previous mark of 4:18.515 set by German Robert Bartko at Sydney Olympics.

Spaniard Sergi Escobar was too strong in the bronze medal ride off against another British Rob Hayles with the winning margin being 4.444 seconds.

During the men's team pursuit, Germany upset the form book by taking the gold in 43.980 seconds. Japan had the silver at 44.246.

Germany's victory made its veteran Jens Fiedler the first track cyclist to take three Olympic gold medals after his win in the sprint in 1992 and 1996.

For the Japanese squad, composed of Toshiaki Fushimi, Masaki Inoue and Tomohiro Nagatsuka, it's their first ever track cycling silver medal.

Defending Olympic and current world champions, France - Mickael Bourgain, Laurent Gane and Arnaud Tournant, had the bronze medal by beating Australia, which was formed by Ryan Bayley, Sean Eadie and Shane Kelly.
