Great Britain's Sarah Storey won her third of a possible four London 2012 Paralympic Games gold medals with a dominant victory in the women's C5 time-trial at Brands Hatch.

The 34-year-old from Manchester won two titles in the velodrome and added gold in the 16-kilometre race against the clock - taking her total tally of Paralympic golds to 10 - on a course which included all the fabled sections of the motor-racing circuit.

Storey finished in 22 minutes 40 seconds and will tomorrow ride in the road race seeking to level Baroness Tanni Grey-Thompson's haul of 11 Paralympic golds.

Mark Colbourne had to settle for silver in the men's C1 time-trial.

Colbourne, who won individual pursuit gold in the velodrome, clocked 25mins 29secs on the 16km course, but Michael Teuber of Germany pipped him to victory, finishing first in 25:16.

It was the 42-year-old Welshman's third medal of his first Games after breaking his back in a paragliding accident three years ago.

"I gave it everything, I'm happy with my silver," Colbourne said.

"I'm very proud of what I've done today."
