Sir Mo Farah won the 10,000m at the World Athletics Championships in London to claim the 10th global gold medal of his career.
Exactly five years on from triumphing on Super Saturday alongside Jessica Ennis-Hill and Greg Rutherford at the London 2012 Olympics, Farah lit up the same venue with another superb performance - arguably his best yet - as his track career heads to a triumphant conclusion.
Farah, who will switch focus solely to road racing at the end of the season, has now won six golds at world championships since 2011 and four Olympic golds - not to mention the five titles he's achieved at European level across the 10,000m and 5,000m.
In a fast-run race which saw his fellow competitors throw everything at him, Farah used his trademark kick off the final bend to get rid of his three remaining rivals before crossing the line in a familiar open-arm style.
Just 40 seconds or so earlier he had suffered a scare as he almost tripped after a coming together with around 300m to go.
However, he recovered his poise to cross the line in 26:49.51 - the fastest time in the world this year.
Joshua Cheptegei, of Uganda, claimed silver, with Kenyan Paul Tanui in third.
The 34-year-old will also bid for an unprecedented third straight long-distance double in world championships history when he runs in the 5,000m final, providing he safely negotiates the heats on Wednesday, next Saturday night. He is 2/5 favourite to win that gold with Sky Bet.
Farah is also a 14/1 Price Boost (from 8/1) to win the BBC Sports Personality of the Year award. Boxer Anthony Joshua is the 8/15 favourite.
"It was one of the toughest races of my life," said Farah. "The guys gave it to me, it wasn't about Mo, it was about 'how do we beat Mo?'
"You had the Kenyans, the Ethiopians, the Ugandans, everybody working as a team against me. Fair play to them, they worked it hard and they chucked everything at me. I just had to stay strong, believe in myself and think, 'I didn't work for nothing, I'm not losing in my home town. I can't'.
"At one point in the middle of the race I wasn't thinking I was going to lose, but I thought 'this is tough, this is tough'.
"I knew at 12 laps to go when they went hard from there it was going to be tough. It was about believing in my sprint finish and knowing that I have been in that position before. It helped a lot having that experience."
Farah hung on during a relentless race which began at a blistering pace with Kenya's Geoffrey Kamworor, Tanui, Cheptegei and Timothy Toroitich putting the pressure on at the front.
But Farah, not beaten over 10,000m since 2011, remained comfortable and made his move with a lap-and-a-half to go - and won in a sprint finish ahead of Cheptegei and Tanui.
His focus now moves to the 5,000m heats on Wednesday ahead of next Saturday's final, his last global race before he switches to the marathon, and he is confident he will recover in time.
He added: "I've got a bad leg. I've got such a long stride I got caught twice and at that point I was just trying to stand up. From that I did hurt my leg and I'm going to see a doctor, a few stitches maybe.
"I am hurt. I just had to be strong. I've got a few cuts and bruises, just recover and get ready for the 5k. I've got enough days."
