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."
Storey's Paralympic career began as a 14-year-old in Barcelona and she won five titles as a swimmer before a series of ear infections saw her turn her attentions to the bike between Athens and Beijing.
Following two golds in 2008, including in the time-trial, Storey now has a hat-trick on home soil in her sixth Games.
She said: "I'm absolutely delighted. It's just amazing to get around the circuit so quick.
"The first thing I'm going to do is see where I would have placed in the men's race."
Storey's comments were maybe slightly tongue in cheek.
The C5 men's race, in which Jon-Allan Butterworth placed 13th, was one 8km lap longer at 24km, but she will be able to see the 16km split for a comparison.
She would have been eighth at that split.
Crystal Lane was ninth in 27:33.
