David Weir made it a fantastic four gold medals at London 2012 by racing to an imperious T54 marathon victory on The Mall.
The 'Weirwolf', released on to the sunny streets of the capital after a week of track domination, timed his sprint finish to perfection to take the title in one hour 30.20 minutes.
With thousands of people lining the route to cheer him on, the home favourite was in a leading group of six racers which broke away early on, content to sit just off the front.
Weir was second behind Switzerland's Marcel Hug in a leading pack of three, also including Australian defending champion Kurt Fearnley with three miles to go.
The 33-year-old came into view of the finishing straight in the lead and pulled away from his rivals to complete a glorious end to a spectacular week.
Victory gave the British wheelchair racing champion a clean sweep of four gold medals after earlier winning the T54 800, 1500 and 5,000 metres titles.
"It's a dream come true," Weir told Channel 4. "Obviously I dreamt about winning all my races but it was going to be a tough order. I really had to dig deep. I did have lots of dreams of winning four gold medals but I think everybody has those dreams. I knew I was capable of doing it.
"The reason I say I only want one gold is because I don't want to put myself under pressure. I want to go into every race not feeling pressured.
"To tell you the truth, every race I did in that stadium I didn't feel under pressure because the crowd was behind you if you won, lost or anything. It didn't matter what position you came in, they were still behind you and they still loved you."
Weir added: "I didn't even know where the finishing line was. That's why I didn't celebrate. There's two lines: the start line and the finishing line. Usually we have a tape, so I was carrying on through. If I looked a little bit moody across the line it's because I didn't know where the line was. I didn't know how close they were so I just had to carry on pushing."
