LONDON — Usain Bolt ended his stellar career in excruciating pain.
The Jamaican great crumpled to the track with a left-leg injury as he was chasing a final gold medal for the Jamaican 4×100-metre relay team on Saturday at the world championships.
Having to make up ground on the anchor leg, Bolt suddenly screamed and stumbled as his golden farewell was shattered by the first injury he has experienced at a major competition.
That wasn’t the only surprise. Britain went on to overtake the United States for gold in a tight finish. Canada’s relay team, without anchor runner Andre De Grasse who missed the championships with his own leg injury, finished sixth.
The 60,000-capacity stadium was primed for one last Bolt show, one last “To the World” pose after a victory, but the injury made it clear why Bolt is ready to retire with his 31st birthday looming. His body can no longer hold up.
His teammates on the once-fabled Jamaican sprint squad were far from unmatchable, too. Bolt had just too much to make up in the final 100 metres as both Britain and the United States were ahead and Japan was even.
With Bolt on the ground, the crowd still went wild when it realized the home team had won gold in 37.47 seconds, .05 seconds ahead of the United States.
It was yet another amazing upset in a championship of so many.
Before Bolt came onto the track, he was consoling Mo Farah, his long-distance equivalent who had just lost his first major race since 2011 when he failed to get gold in the 5,000 metres.
Farah also was bidding farewell to the track, coming up short of his fifth straight 5,000-10,000 double at major championships in a sprint against Muktar Edris of Ethiopia.
“I gave it all,” Farah said. “I didn’t have a single bit left at the end.”
Instead, Tori Bowie was the unlikely first double gold medallist at the championships, anchoring the U.S. team to the 4×100 relay title ahead of Britain and Jamaica.
At the same time, Allyson Felix, running the second leg on the winning team, earned a record 15th medal at the world championships in a career going back to 2005.
Bowie, who won the 100 metres this week, ran a strong anchor leg, leaving behind the opposition to finish in 41.82 seconds.
“Two gold medals is amazing for me,” Bowie said. “We are on top of the world.”
Britain took silver in 42.12 and two-time defending champion Jamaica earned bronze in 42.19.
If Bolt and Farah were about farewells, the decathlon was about renewal in the wake of the retirement of two-time Olympic and world champion Ashton Eaton. And Kevin Mayer is the new “world’s greatest athlete.”
The Frenchman produced a dominant performance over two days and 10 events, ending with a celebratory 1,500 metres.
Mayer won with 8,768 points. Rico Freimuth took silver with 8,564 points, while German teammate Kai Kazmirek was third with 8,488.
Mayer is the first Frenchman to win the title. He had only one scare during the two days of competition — when he scaled his opening mark of 5.10 metres in the pole vault on his third and last attempt. Canada’s Damian Warner finished fifth.
Johannes Vetter of Germany won the javelin title with an opening throw of 89.89 metres. The German beat Jakub Vadlejch of the Czech Republic by 16 centimetres. Another Czech, Petr Frydrych, took bronze with a last throw of 88.32 metres.
In the high jump, Mariya Lasitskene of Russia cleared 2.03 metres to win ahead of Yulia Levchenko of Ukraine and Kamila Licwinko of Poland.
There was at least one veteran who did produce Saturday as Sally Pearson got another gold medal at the Olympic Stadium in London after missing much of the past two seasons because of injury.
Five years after winning the 100-meter hurdles at the London Games, Pearson won the world title in 12.59 seconds.
Dawn Harper-Nelson of the United States was second, .04 seconds behind, and Pamela Dutiewicz of Germany took bronze in 12.72.
