Mo Farah delivered under extreme pressure to add the world 10,000m title to his Olympic gold with a brilliant performance in Moscow.
Farah paced his race to perfection, clocking 27:21.71 to complete his set of major championship titles over 25 laps.
The pedestrian early pace played into fast-finishing Farah's hands and he hit the front in the concluding stages in a textbook display of distance running.
And down the home straight the double Olympic champion determinedly held off Ethiopia's defending champion Ibrahim Jeilan - reversing the result from two years ago in Daegu. Kenya's Paul Tanui completed the podium.
Farah becomes the first British athlete to win a 10,000m world title since Liz McColgan in 1991 and the first European man to win over the distance at the Worlds since Italian Alberto Cova in 1983.
And he'll now look for another golden double in the 5,000m next week.
"I was determined not to lose again, I had that experience from two years and I saw him coming," said Farah.
"It was a tough race, I covered every move and I nearly went down a couple of times but thankfully stayed on my feet. The guys were trying to take it out of me, so I'm delighted I held on for the win.
"I didn't want to lose again, I remember how I felt when I finished second in Daegu. I just dug in there and it was enough.
"It's just nice to win, this was the medal missing from my collection and I really wanted it."
