Great Britain's men claimed a stunning 4x100m relay gold at the World Championships as Usain Bolt pulled up injured in his final ever race.
On a febrile night of track and field, Mo Farah's own finale ended with 5,000m silver as he was beaten in a global final for the first time in six years.
But with the young GB women's sprint quartet storming to a silver of their own it felt like a generational shift as the stadium came alive just as it had at the 2012 Olympics.
Never before has a British team won a world sprint gold, but the quartet of CJ Ujah, Adam Gemili, Danny Talbot and Nethaneel Mitchell-Blake ran a near-perfect race to hold off the fancied US team, with Japan taking bronze as Bolt collapsed halfway down the home straight.

It was a horrible way for Bolt to end his career, his hamstring appearing to go as he attempted to chase down the two men in front of him.
A wheelchair was brought to his side before he was helped to his feet and managed to limp away, but it means he leaves his final championship with only a bronze from the individual 100m to show.
