Four records fall at Paralympic velodrome

AP - Australian cyclist Susan Powell set one of four world records in the opening session of Paralympic competition at the London 2012 velodrome.

Powell qualified quickest in the women's C4 3km individual pursuit with a time of four minutes 3.306 seconds on Thursday.

She will meet USA's Megan Fisher (4:06.599) in the final, while Alexandra Green of Australia (4:07.152) and Canada's Marie-Claude Molnar (4:11.678) will be vying for bronze in the event.

There were two world records in qualifying for the women's C1-2-3 3km individual pursuit.

Zeng Sini of China, a C2 rider, clocked 4:19.841 to book a meeting with Simone Kennedy of Australia (4:23.450) in the race for gold.

Australian Jayme Paris set a world record of 4:40.123 but the mixed-classification event was not factored, and the C1 rider did not advance to the medal rounds, placing eighth.

Australia dominated the final event of the morning session, the men's blind and visually impaired 4km tandem pursuit.

Two Australian pairings advanced to the final, where Kieran Modra and Scott McPhee (4:18.752) will meet Bryce Lindores and Sean Finning (4:21.219) will race for gold.

The battle for bronze will be between Spain's Miguel Angel Clemente and Diego Munoz (4:24.539) and Ireland's James Brown and Damien Shaw (4:25.557).

Great Britain's Sarah Storey set the session's other world record, clocking 3:32.170 seconds to advance to the gold medal ride-off of the women's C5 3km individual pursuit.
