2017 World Athletics: Great Britain win 4x100m gold as Usain Bolt's career ends in disappointment

The British quartet of CJ Ujah, Adam Gemili, Danny Talbot and Nethaneel Mitchell-Blake were 10/1 third favourites with Sky Bet but pipped the United States to gold in a world-leading 37.47 seconds, which was also the third fastest in history.

Bolt was trailing in third when he pulled up on his anchor leg before collapsing to the track as his bid for a 20th global gold came to an agonising end.

Britain's winning time, a combination of Ujah's perfect 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. The USA took silver in 37.52secs and Japan the bronze.

Mitchell-Blake, who had to settle for fourth in the individual 200m, roared with delight at the finish in scenes similar to Mark Lewis-Francis' cries of delight when he crossed the line at the 2004 Athens Olympics to earn Britain sprint relay gold.

The victory made it a night of double sprint relay joy for the hosts as the women's team of Asha Philip, Desiree Henry, Dina Asher-Smith and Daryll Neita won silver in 42.12s.

The tale since Athens for Britain has been one of missed chances and baton blunders. But no more, and the joy amongst the team was evident at the finish.

Ujah told BBC Sport: "I am proud of these guys and those behind the scenes. It is crazy to do this in London."

Gemili, controversially overlooked for selection in the individual 200m, said: "It's crazy, honestly a dream and a reality tonight. Wow."

"We are world champions at home. We will never get this feeling again," Talbot added.

Mitchell-Blake said: "I wasn't sure if I had won or not, I gave it my all, but I could see Christian Coleman out of the corner of my eye. The feeling of euphoria was from infinity. I can't register it. We smashed the British record to pieces."

While Britain celebrated, though, there were contrasting emotions for Bolt in the final race of his career.

The 30-year-old pulled up on the home straight as he sought to chase down the United States and Britain, hobbling for a few strides before falling to the track.

His team-mates gathered round him and the 19-time global champion was helped to his feet and limped over the line, applauding the crowd as he did so.

It was a sad way for Bolt to bring the curtain down on the greatest athletics career the world has ever seen since his record-breaking runs and gold medals at the 2008 Olympics.

The greatest sprinter of all time will be remembered for racking up 19 major gold medals overall throughout his legendary career, with 11 won across five world championships and the other coming from his three Olympic Games dating back to Beijing, when he burst onto the scene in record-breaking fashion.

The only other times he failed to medal in any individual or relay event he entered since then was when false-starting in the 100m final at Daegu 2011, while the 4x100m gold he helped Jamaica win at the Beijing 2008 Olympics was stripped earlier this year due to Nesta Carter's failed drugs test.

As if we needed any further indication that Bolt was special, he is due to perform one final lap of honour round the London Stadium on Sunday night.

As well as his 100m and 200m world records, he also surely holds the one for most laps of honour performed too.

But, after four successive sprint relay golds at the World Championships, Jamaica's reign is over.
