Taking his final bows after his gold medal performances at last summer's Rio Olympics would have sealed an unblemished legacy. Neither is the sport he competes in - distance running.
They ranked fifth fastest going into the final, trailing the US, Britain, Germany and Switzerland.
Sir Mo Farah admits he will be emotional when he finally brings the curtain down on his glittering track career.
For a decade, he has been this intimidating figure on the track for his opponents - winning all the Olympic or world championship finals he was in, except one hiccup when he false started in the 100m final in Daegu world championships in 2011.
Whenever the giant screen inside the stadium showed him doing the baton exchange practice with his Jamaican team-mates in preparation for the 4x100m relay race at the warm-up arena, the capacity crowd cheered loudly.
Where is the hypocrisy in that statement? You get this urge to yell at the TV and warn them that he's right behind them, but they already know this-Gatlin peeked over his shoulder and searched for Bolt as his lead dwindled, he was afraid.
The list of shame is star studded. His sentence was reduced to six months on appeal. There is no doubt that he will definitively leave the scene on a final rite. He ran his last individual race, the 100m, last Saturday, managing only a bronze; no fairytale finish for him.
Names like Carl Lewis and Jessie Owens are revered for their dominance at 100 meters.

Lewis' response in 2003?
Part of the reason media hellfire rained down on Johnson was because he wasn't smart enough to play the wronged naïf. "I personally don't think it [the bronze medal] has changed what I have done in any way", Bolt said. "It feels like second nature because we work well together". What's more, Gatlin denies him the crutch of old age, which Bolt could have leaned on to justify his retirement and/or rationalize this loss.
Equally as heartwarming was the moment that Ahmed Farah walked off the track to a cheer as loud as any received by a Team GB competitor. What do you with the fact that the conduct of this lovable man's coach, Alberto Salazar, was described in a US Anti-Doping Agency report just past year as "patently calculating, misleading, and dishonest"?
"They are definitely running alongside us, and that's what we need".
American athletes have taken front and center at these Championships already and, watching the operations of the US Team, it is little wonder why.
Clamping down on drugs in athletics shouldn't a beauty contest. A friend of mine named Mick had one of his legs amputated, he told me that one of the things he regretted was getting so angry with himself that he never managed to run a marathon under three hours.
