The BBC commentator is brilliant at what he does but the one time he possibly hit a bum note was at the Rio Olympics a year ago when he rather over-excitedly extolled "they succumb to the inevitable, bow to his superiority" as Farah streaked away for this third Olympic gold in the 10,000m.
Farah hung back in the lead pack in the early stages of the race as Kenyan two-time cross country champion Geoffrey Kamworor continued to force the pace with Tanui close behind as they tried to tire Farah.
Though perhaps not a shockingly slow time, given compatriot Julian Forte dipped clocked 9.99secs and youngster Christine Coleman went 10.01secs, it was short of the usual standard Bolt has delivered over his brilliant career.
Bolt's true farewell was to come 24 hours later in the finals of the 100m, not the heats he had messily navigated on Friday's opening night, whereas Farah's race was a final farewell, at least in that event.
Mo Farah dug out a performance of guts and guile on Friday night to gather another gold in the 10,000 metres. It just started hurting and then I just didn't want to get lapped.
The world and Olympic champions had won gold in the 10,000 meters in 2012, 2013, 2015, 2016 and now 2017.
Joshua Cheptegei of Uganda won silver in 26:49.94 and Paul Tanui of Kenya earned bronze in 26:50.60. "But I just had to be mentally stronger and think I didn't work this hard for nothing". As expected, the likes of the Kenyans, Ethiopians, and the Ugandans worked with each other to try and stay in the best position. "I genuinely believe that he will again win two gold medals".
From there on the race unfolded into the inevitable, and became all about Farah, who despite producing these unbreakable displays on the track, still can't distance himself from the shadow of drugs, specially his association coach Alberto Salazar, now being investigated by United States anti-doping.
'Hard races have to be run.' None harder than the one that brought his most recent medal. "I've got a few cuts and bruises, perhaps I will need a few stitches". First up was Jessica Judd, putting up a PB after running a very gutsy heat hitting the front at the start to make sure she could get in a fast enough time to avoid the agonising wait.
"On encouraging the crowd: "I just wanted to play with the guy's head". I just have to do a bit more here and there. "It helped a lot having that experience".
And it will take something special from his opponents to deny him that 11th and final track crown before he switches to the marathon where even greater riches await. I'm not very fond of these blocks. It was the second fastest heat of the three, seeing Sarah McDonald waiting surreptitiously by the scoreboard to see if she had qualified as she nabbed the final fastest loser qualifying spot.
