So, of his rivals in Friday's 10,000m, who can get close to Farah, who again is not the quickest in the field going into the championships?
Farah was content to sit in sixth and seventh as Eritrea's Aron Kifle then took it up, followed by Uganda's Timothy Toroitich and then Cheptegei again, and only at 800m did the 34-year-old make his move. Boxer Anthony Joshua is the 8/15 favourite.
However as many people are asking how athletics will be able to cope without Bolt and his engaging showmanship, perhaps unfairly the same has not been said about the vacuum that Farah will leave in his wake.
When you think of Mo Farah's great victories over the incredible past five years it is hard to separate them from the soundtrack of Steve Cram's high-octane closing-stage commentaries.
Farah believed he had come through the biggest test during his six-year unbeaten streak in major championships as he faced a concerted effort from his Kenyan, Ugandan and Ethiopian rivals. "They worked that well, fair play to them".
"I just had to stay strong, I was just thinking that I can't lose in my home town".
With retirement looming, the four-time Olympic gold medallist told The Mirror: "I know there's a target on my back going into this race. It helped a lot having that experience". "I have to get the start together as I can't keep doing this". I've got such a long stride I got caught twice and at that point I was just trying to stand up.
"I am hurt, I just have to be strong now and see the doctors", said Farah. "It's nothing that concerns me and I've got enough days to recover, rest up, to be ready for the 5000".
"I got spiked somewhere in the race, it's fine, it happens". A few months later, Bolt claimed gold in both the 100m and 200m at the world championships in Moscow at Gatlin's expense. He'll be racing the 10,000-meter and 5,000-meter events in front of thousands of fans on his home track one last time. He is halfway there in London.
Kamworor exchanged the lead with Cheptegei performing the same role as he had in the Olympic final in Rio. "This is the result and I'm very much happy because my star has started shining", he said.
But Farah, unbeaten over 10,000m since 2011, remained on course to claim a 5,000m and 10,000m double for a third time and now has 10 global titles.
He will be joined by former Olympic, European and World long jump champion Greg Rutherford, who will be the expert analyst for Eurosport during the event.
No normal athlete - in the original meaning of that word - wins three World 10,000m titles in succession, another footnote being his last 1km split of 2:28.82.
Farah will now hope to complete yet another long-distance double - the feat he has completed at the last four global championships - with victory in next week's 5000m.
Still things became tense in the final lap as Tanui came in contact Farah. "Yes, 2012 kicked it all off but tonight they really took it to him and made it a tough race and he handled it".
