It was Katherine Grainger and Anna Watkins' day after all. Three previous silvers for Grainger and a bronze for Watkins were turned into gold on Eton-Dorney lake in the space of six and a half epic minutes.
The GB women's double scull led from the outset and the script went to plan. Australia tried coming back on them at 1300m but could not derail what became an emotional ride down the course for them and for the nation.
"We knew we were capable of this in our heads and in our hearts but we still had to deliver it", said Watkins.
Asked what it was like to finally be an Olympic Champion Grainger said: "It's very hard to put into words but it's every bit as wonderful as you might think".
Before their final the young GB men's pair of Will Satch and George Nash had wowed the crowd with a bronze on their Olympic debut in the men's pair.
"It shows if you do the training and you stick to the programme you can do it", said Satch.
Whilst Grainger and Watkins were still letting it sink in, Alan Campbell won bronze in the men's single scull - a medal at his third Games of trying in a race won by his friend Mahe Drysdale from New Zealand.
Much earlier the GB men's quadruple scull of four-times Olympian Matt Wells, Stephen Rowbotham, Charles Cousins and Tom Solesbury produced a strong performance to hold onto fifth place in their final.
RACE REPORTS AND QUOTES
Drawn side-by-side with their main rivals, Kim Crow and Brooke Pratley of Australia, today's women's doubles sculls race had a somewhat gladiatorial feel about it.
Grainger and Watkins were unbeaten before today and are double World Champions, the Australians won silver behind them in Munich at the final world cup after a season disrupted by injury.
All that Aussie-GB rivalry distilled down into mere minutes. The scene was set.
Watkins and Grainger were peerless. They led from the outset and it seemed difficult at time to see any other boat in the race. Australia briefly threatened at 1400m, they kicked hard but could not attack the British lead.
Gold for GB, gold for the nation's favourite rowing daughter and a first gold for Watkins whose engine and dedication and personality have dovetailed so well with Grainger's racing head and determination.
"You feel that you are in a stadium here .The crowd seem to be in front of you and around you and behind you. It's incredible", said Watkins. "We even had time to enjoy it which his more than you could ever dream of".
"It will sink in eventually I'm sure but I bet I still wake up tomorrow and check it's stlll there (the medal)", said Grainger.
Will Satch and George Nash have been one of the surprise packages of the 2012 season for Great Britain. As previous World U23 medallists they were desperately disappointed not to make the cut for the eight in their first season as seniors.
That disappointment will have been tinged by a degree of success already enjoyed at world cup level.
In the semi-finals at Eton Dorney they took the race by storm, leading from the front to win. Today they faced the colossus of Kiwi pair Eric Murray and Hamish Bond - multiple World Champions and, like the American women's eight, one of the stand-out crews of World rowing for the past quadrennium.
Drawn in lane five, after the last-minute shuffling of lanes to ensure fairness on the course, the duo would race side by side with the Kiwis.
But it was the French who went out to an early lead, only to be overhauled at 750m by the New Zealanders who went onto an expected and peerless victory.
Behind them Satch and Nash held their nerve and their rhythm to win bronze in 6:21.77 in a magnificent debut for this significant prospect for more honours in Rio.
"I have so much respect for this guy", said Satch of Nash. "I've known him since we were 14 and raced against him many times. It's an absolute honour to race with him here".
"From the word go this guy gave so much power", said Nash of Satch.
The GB men added a second medal of the day when Alan Campbell emerged from a ding-dong battle with Lassi Karonen of Sweden to take bronze behind one of his great friends Mahe Drysdale of New Zealand with the Czech Ondrej Synek in silver.
Alan Campbell is part of a unique trio of rowers from Coleraine at the 2012 Games. He will have watched yesterday whilst his team-mates Peter and Richard Chambers took silver in the lightweight four.
Today it was his chance to take centre stage after a trouble-free six-week lead into the Games - in contrast to Beijing when he had an infection.
He tracked Drsydale and Synek throughout and broke Lassi Karonen of Sweden with 600m to go. "I wasn't going to let him through", he said.
Earlier the men's quadruple scull of Tom Solesbury, Charles Cousins, Matt Wells and Stephen Rowbotham kicked off the day's racing for GB. Drawn in lane two, they knew they would have to battle the elements as well as the best crews in the world.
Croatia the World Champions were the favourites to win but Germany went out fast in lane six. They led by over half a length from Croatia for the first half of the race with GB in lane two well placed in third. Australia came up to challenge GB as the race moved into the second half.
Germany pulled further ahead of Croatia and the Australians pushed past GB as did the New Zealanders in the final 300m. So fifth for GB in a time of 5:49.19.
WHAT'S NEXT FOR THE ROWERS?
Tomorrow sees the final day of rowing at the 2012 Games. Britain has three boats in action: the men's four and the two lightweight men's doubles.
Andrew Triggs Hodge, Peter Reed, Tom James and Alex Gregory are the men's four and they race at 11.30.
Reed, Hodge and James are defending champions whilst Gregory and James are reigning world champions. They face a potentially tough race with Australia as the main opposition.
Kat Copeland and Sophie Hosking are the lightweight women's double whose final is at 11.50. They rowed through the Greek World Champions in the semis to qualify for tomorrow's final.
The final crew to race at the Olympic regatta for Great Britain will be the defending Beijing champions Mark Hunter and Zac Purchase in the lightweight men's double scull. Their race starts at 12.10.
