Australia's Susan Powell won the women's Individual C4 Pursuit and Kieran Modra and Scott McPhee triumphed in the day's final event, the men's Individual B Pursuit, after Britain's Sarah Storey won the Individual C5 Pursuit.

Li won gold with a C1 world record of 1:13.009, converted to 1:05.021, with Britain's Mark Colbourne second in 1:16.882, converted to 1:08.471, and Tobias Graf of Germany third after setting a C2 world record of 1:15.858, converted to 1:09.979.

'In training I've been performing very steady,' Li said. 'My performances have been going up, so I was expecting to win.'
