It made Farah the first Briton, man or woman, ever to win the Olympic 25-lap title – Mike McLeod had come closest with his silver in Los Angeles in 1984 - and the first since Liz McColgan back in Tokyo 1991 to beat the world over the distance in a major championship.
It also made up for his heartbreaking near-miss in last year’s world championship 10,000m when the Londoner lost out in a sprint finish with little-known Ethiopian Ibrahim Jeilan.
On that occasion, though shattered by the loss after another all-conquering season, Farah responded with great conviction a few days later to become the first British man to win the world 5,000m title.
Now he has the opportunity here next Sunday to add the Olympic 5,000m crown which has previously always deserted all of Britain’s brilliant male endurance runners and to join the immortal double winners like Lasse Viren, Miruts Yifter and Kenenisa Bekele.
Dangers lay everywhere, not least with the chances of the powerful Kenyan and Ethiopian trios to gang up on the home favourite.
In the early stages, Farah found himself jostled and hassled but he did not panic as he fell back and the Eritrean, Zersenay Tadese, kept injecting surges after a fairly sedate first 2km.
The home time boy kept his concentration even when he was being intimidated, running a mature race and with two laps left there were still 12 in contention. But with 450m left, Farah made his move, sped ahead and defied all the opposition’s efforts to catch him.
This seemed an incredible victory for Farah after his calamitous 2008 Olympics, when he failed even to reach the 5,000m final. Yet that was the spur to make him decide on a completely new approach to his running in a bid to beat the world.
Moving with his wife, Tania, who had been his childhood sweetheart, to America, and his stepdaughter, Rihanna, Farah threw in his lot with the brilliant Cuban-born coach Alberto Salazar, committing himself to a tough new regime in Portland, Oregon.
It was the work there which transformed him into a distance runner for everyone to fear. His 10,000m defeat in Daegu last year had been his only reverse of an all-conquering year and, though this season had started with a disappointing defeat in the world indoor championships, his form outdoors had hardly deteriorated as he entered last night’s race on the back of seven races unbeaten outdoors this summer.
The acclamation from the crowd, just as deafening as it had been for Ennis’s wonderful performance, told of just how popular this man is. You can undersatand why; if Ennis is the girl next door, Farah is the good lad who everybody within the sport adores.
He is funny, laid back, boyishly charming. He beat TV’s Cube which everyone laughed was miraculous enough. Now he has beaten the world and has to be thought of, simply, as one of the greatest athletes Britain has ever produced.
Yet we may have seen nothing yet. On Wednesday, the heats of the 5,000m begin and the MoBot celebration may just be about to go completely global.
