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 ride in the road race on Thursday seeking to level Baroness Tanni Grey-Thompson's haul of 11 Paralympic golds. Storey claimed a supreme victory by 1min 34secs over Anna Harkowska of Poland and Kelly Crowley of the United States, with team-mate Crystal Lane ninth in 27:33.
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: "To be anywhere near Tanni is incredible. I can't believe I've been put on the same page as her. Tanni's a good friend, an incredible athlete and such a lovely girl. Just to even be thought of her in the same breath is an honour, whether or not tomorrow goes my way.
"The road race is a road race, you can never tell. The girls will all be gunning to beat me after this week. I'll have to keep my wits about me and see what happens. I'm marked everywhere I go. I'll see what I can do and hopefully have the legs for it tomorrow."
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."
