With Jamaica pulled up Great Britain ran home in a victory as surprising as Jamaica's last place, ahead of the U.S. in silver and Japan bronze.
He got up with the help of his teammates Blake, Omar McLeod and Julian Forte to eventually limp across the finish line and offer the crowd a tearful wave.
He edged out American Paul Chelimo in a desperate dash for the line, the last mile of a hitherto slow run race run in just under four minutes.
"It was cold. Usain said to me "I don't like this", because we keep on warming up, and sitting, and warming up".
Team GB's first ever Men's 4x100m World Championship success followed the silver medal won by Team GB Women. I think it got the better of us. "40 minutes and two medal presentations before our run", said Yohan Blake, who branded the wait as "crazy".
Britain's winning time, a combination of Ujah's ideal reactions, flawless changeovers and a superbly-timed dip from Mitchell-Blake to cross the line ahead of 100m silver medallist Christian Coleman, was a new national record, erasing the 18-year-old mark of 37.73.
Burney puts the sword to reigning EPL champions Chelsea
All seemed lost when Fabregas earned a second yellow card for lunging in on Cork nine minutes from time. In the next game I'm not sure whether Pedro is ready but for sure we'll have (the other) two players.
Bolt may not have led Jamaica to a glorious finale anyway, though, as he took the baton well behind eventual winners Great Britain and the US.
Gatlin, who beat Bolt to gold in the 100m last Saturday, agreed with the complaints and laid the blame at the television scheduling for the event.
The penultimate day of the championships also has former 100 metres hurdles champion Sally Pearson of Australia going up against world record holder Kendra Harrison of the United States for the title.
"I think it was the elements. He is still the best in the world", Gatlin said.
"They were holding us too long in the call room", Yohan Blake told the media. He was running out there cold.
It has been a disastrous farewell championships for the world's fastest man who was surprisingly beaten in the 100m, his final individual race of his career, where he took bronze.
