Perhaps this was a step too far into greatness, even for an athlete like Farah.
Indeed, Farah was only fourth coming into the homestretch and chased down Edris fast with the line approaching; just not fast enough, Edris winning in 13:32.79, slow by championship standards but in tactical execution perfectly impressive. It's been awesome but it's been a long journey.
"I have to focus on myself".
"I don't think there was any more I could have done". It's not an excuse, but it took a lot more out of me than I realised.
Yet just like Usain Bolt in the 100 metres the previous weekend, it did look a race too far for the tired Briton.
Edris celebrated by holding his hands up over his head in the "Mobot" gesture that Farah had invented for his succession of victories.
Edris celebrated his victory with Farah's iconic "Mo-bot" celebration, while the silver medallist's astonishing career accomplishments were recognised by a rapturous ovation from the adoring crowd.
Into the last 800m however and they ate Tiernan up, though the truth is Farah never looked entirely comfortable: they hit the bell in 12:40.17, and Farah was chasing all the way down the backstretch, unable to get himself in front when he either wanted to or needed to.
"I didn't have much support but we did it". That's why I did the Mobot.

The Pentagon declined to provide any details but said that all operations are conducted in accordance with worldwide law. The whole territory of the South China Sea, which is believed to be extremely rich in energy resources, is disputed.
Kenyan-born Chelimo took the bronze in 13:33.30 while Farah's late burst also consigned another Ethiopian Yomif Kejelcha to fourth place in 13:33.51.
In the dying meters, Farah shot down the inside to overhaul American Paul Chelimo and clock 13:33.22.
It was a poignant sight after so many Farah celebrations down the years to see him lying on his back, exhausted and forlorn with his arm draped across his face, but his rivals were not about to let the moment pass without celebrating him.
Muktar Edris of Ethiopia has broken the hold of Mo Farah on long-distance running, outkicking the Briton over the final 200 meters to win the 5,000 meters at the World Athletic Championships in London.
Farah and his team-mate Andrew Butchart had tried to break up the field with 600 metres to go in a race that had been run at generally a very slow pace. They had a game plan and that was that one was going to sacrifice themselves, but I gave it my all.
"They worked as a team, the better man won".
"My legs had it on the home straight".
"I got boxed in early on (in the final charge) - it doesn't normally happen - and couldn't get out".
