The night began with a disappointment for the hosts, as the British distance star Mo Farah’s 10-final winning streak at global championships ended in the 5,000 meters. Competing in what he said was his last track event before a switch to road racing, Farah could not produce his traditional devastating kick. He finished second behind Ethiopia’s Muktar Edris, and the American Paul Kipkemoi Chelimo won the bronze.
But the men’s relay turned the night around for Britain, and Mitchell-Blake celebrated by sprinting down the track again, this time with the baton between his teeth.
Meanwhile, Bolt’s teammates rushed to help him as he lay on the track in the same stadium where he and his countrymen set the world record in this event, 36.84 seconds, at the 2012 Olympics.
Kevin Jones, a doctor with the Jamaican team, said his preliminary diagnosis was that Bolt had suffered an acute muscle cramp in his left hamstring, although Jones could not rule out the possibility of a muscle tear.
“I think a lot of the pain was from disappointment,” Jones said, tapping his heart, “from not being able to finish the race. That was the main thing.”
He said that a slight delay at the start of the race — because of the length of two medal ceremonies preceding it — might have contributed to Bolt’s situation.
The Jamaican sprinters said they had been kept too long in the “call room,” the holding area that serves as a way station between the warm-up track and the main stadium.
“Usain was really cold,” Blake said afterward. “In fact, Usain said to me, ‘Yohan, I think this is crazy, 40 minutes and two medal presentations before our run.’”
Omar McLeod, who ran the first leg for the Jamaican team, also criticized the delay.
“We were really trying our hardest to stay warm and keep upbeat, but it was ridiculous,” he said.
Still, none of the sprinters from the teams that did win medals had a problem similar to Bolt’s, not even Justin Gatlin, the 35-year-old American who had upset Bolt in the 100-meter sprint here (and who was booed again by some members of the sellout crowd during introductions).
“I personally think we were held underneath the stadium a little too long without our clothes on,” Gatlin said, referring to the athletes’ warm-up suits. “It was pretty drafty, and I lost all my sweat and body heat. I think a lot of us were jostling around trying to stay warm a little longer than usual.”
Bolt won three gold medals at the London Games, confirming his status as one of the greatest Olympians in history. He added three more golds at the 2016 Olympics in Rio de Janeiro, but this season proved to be one too far for Bolt, who will turn 31 this month. At these championships, he had to settle for a bronze medal in the 100-meter race. And then came the relay.
No morning person, he made an exception this time and took part in the early heats, running the anchor leg and helping Jamaica win its heat to qualify for the final. Bolt put on a good show before the final, too, joking with the mascot in the corridor leading to the track and playing to the crowd once he emerged from the tunnel.
But there would be no grins or laps of honor after this relay was run, and if this was indeed his final official race, it was hardly a reflection of the mood and victories that preceded it.
Bolt looked anything but invulnerable as he hopped to a halt, shouting an epithet while his rivals continued to accelerate. He looked anything but superhuman as he fell to earth, although he did manage a somersault on the way down.
Though he was eventually able to rise to his feet, eschewing the wheelchair that had been brought for him, and hobble across the finish line long after the race ended, with his Jamaican teammates walking slowly and grimly beside him, he soon dropped to the track again and grimaced.
He later rose again and limped away without speaking to reporters. He received treatment from his longtime massage therapist before returning to the team hotel.
“I think that no one wants to see Usain go out like that,” Gatlin said at the medalists’ news conference. “I think all of us have been inspired by him in some form and some way in his career. He’s done so much from 2008 on to now, so I think we can look past everything that has happened in these championships and congratulate him on his legendary career.”
If this was truly the end, Bolt finished with 14 career medals in the world championships, 11 of them gold, and with eight Olympic gold medals.
But there was no final flourish for a man who has been not only one of global sport’s great athletes, but one of its great entertainers as well.
