Jessica Ennis, Greg Rutherford and Mo Farah tonight struck gold for Britain in front of 80,000 fans at the Olympic Stadium on Saturday night.
Ennis started the party with a dominant victory in the heptathlon before Rutherford leapt to victory in the long jump, the 25-year-old's winning jump of 8.31 metres coming at precisely the same time as Ennis was being introduced to the fans before her final event, the 800m.
And Farah then rounded off an astonishing three triumphs in the space of 45 minutes with a blistering last lap in the 10,000m, completing it in 53 seconds to take gold ahead of American training partner Galen Rupp.
Ennis had a commanding lead going into the 800m but still stormed to victory to improve her national record to 6,955 points and win by an amazing 327 points from world champion Tatyana Chernova.
"I can't believe I've had the opportunity to come to my first Games in London and won an Olympic Gold medal. It's unbelievable," said the 26-year-old from Sheffield, who missed the Beijing Games after suffering a career-threatening foot injury.
"It's a massive relief because it's so hard getting through a heptathlon anyway, it just such a tough event.
"But to have come into this event with all that pressure, and everyone just saying, 'Oh, you're going to win gold, you're going to win gold' - and I know how hard it has been to win it - yeah, I just can't believe I've done it."
Rutherford, who headed the world rankings in 2012, took the lead in the second round with a jump of 8.21m and was never headed, the 25-year-old from Milton Keynes then jumping 8.31m in the fourth round to extend his lead.
Australia's Mitchell Watt (8.16m) took silver and American Will Claye (8.12m) bronze, while Rutherford's British team-mate Chris Tomlinson (8.07m) had to settle for sixth.
World 5,000m champion Farah had thought his race would not come down to the last lap as his rivals feared his sprinting speed, but in the end that was what happened and Farah hit the front at the bell to time his finish to perfection.
The Somalia-born 29-year-old collapsed to the track before being greeted by his seven-year-old stepdaughter Rihanna and wife Tania, who is expecting twins in September.
Tonight Rutherford was still finding it hard to believe he had achieved his life's ambition.
"I don't think I'll ever get bored of hearing that," he said, when reminded he is now an Olympic champion.
"That is the most amazing feeling in the world."
Giving a highly emotional interview, Rutherford said: "I have the most amazing parents you could possibly have, a beautiful girlfriend, just everything.
"I can't tell you how much everyone has worked so hard for me, as well as myself.
"It's been a long process.
"I thought I was going to jump further than that but I don't care - I'm Olympic champion."
Speaking on BBC1, he added: "What a night for British athletics. Three gold medals out of a possible three really.
"The crowd were absolutely incredible.
"I don't think it's sunk in properly. This is what I've dreamt of my entire life.
"I knew I was going to be a sportsman. When I picked athletics I knew I wanted to be an Olympic champion.
"And I get to do it in London... I might wake up in a minute."
Jamaica struck the first blow in the battle for sprint supremacy as Shelly-Ann Fraser-Pryce successfully defended her Olympic 100m title.
Fraser-Pryce edged out America's world champion Carmelita Jeter to win in a time of 10.75s, with Jeter just 0.03s behind and Jamaica's Veronica Campbell-Brown taking bronze in 10.81s.
Usain Bolt and Yohan Blake will hope to continue Jamaica's dominance in the final of the men's event tomorrow.
Ennis said of her glorious night, after putting the seal on two days of a one-sided competition: "I'm so shocked, I can't believe it.
"I couldn't let myself believe it till I crossed the finish line in the 800 metres.
"I'm so happy.
"I want to thank everyone here and my family and everyone who's supported me. Everyone who's worked with me."
Ennis had to sit out the 2008 Olympics due to injury, a blow which was difficult to accept at the time.
A tearful Ennis told BBC1: "After Beijing, everyone said we were going for another four years to finish what we started.
"I just had to give it everything at the end.
"I just wanted to make sure I gave them such a show, brought it home and left everything on the track."
She was non-committal over whether she will also compete in the 100 metres hurdles - the event in which she set a new British record yesterday in the opening event of the heptathlon.
"I think I need to savour this moment and enjoy it," she said.
"It's been a really stressful year and there's been a lot of pressure.
"Everyone thought I was going to win gold from day one."
Farah told BBC1: "I've never experienced something like this, it doesn't come around that often and to have it on your doorstep with that amount of people supporting you and shouting your name...it's never gonna get any better than this. This is the best moment of my life.
"It's just something that I've worked so hard for.
"It's just the grinding and hard work and 120 miles a week, week in, week out and long distance events and what you put into it is what you get out."
He added: "I want to thank everyone who has supported me from my childhood until now. Without all those people that wouldn't have happened and I've just got to enjoy this moment I guess."
what do you think?
So proud to be British. Ennis was under pressure as the face of the Games but she delivered.
