Usain Bolt's 100m world record of 9.58 seconds has stood for 11 years.
The Jamaican sprint king retired three years ago, with no athlete looking like they will eclipse his achievement any time soon. Here, we look back at his heroics at the 2009 World Championships in Berlin.
The build up
Bolt was already the 100m world record holder having posted 9.69 seconds when winning Olympic gold in Beijing in 2008.
And in the semi-final he teased that something special might be on the cards when he clocked 9.89 seconds, despite easing down at the finish.
It was a warning to his rivals and a reminder to the Berlin crowd to keep watching.
It was a year to the day since he lowered the 100m mark in Beijing and the Jamaican powered off from the start.
He was in control of the race after just 30m, with a world record already looking possible.
The hopes of Tyson Gay and Asafa Powell - who eventually came a distant second and third - were over before they had already begun.
Bolt stormed across the line a huge 11 hundredths of a second faster than his previous record.
Four days later, he set a new 200m record of 19.19 seconds.
The closest Bolt came to his own record was a 9.63 seconds run at the London 2012 Olympics - where he defended his 100m crown.
By the time he was coming close to retirement in 2017, the Jamaican's best was 9.95 seconds and he closed his career with a bronze in the 100m at the World Championships in London.
It came just before a dramatic last race in the 4x100m final where he crashed to the ground after tearing his hamstring with 50m remaining.
The heirs to the throne
Christian Coleman's 9.76 seconds at the World Championships in Doha in 2019 was the fastest run for four years and the sixth quickest in history but still nowhere near Bolt's time.
The American was the favourite for the Olympic title before the Tokyo Games were delayed until next year by coronavirus.
Canada's Andre De Grasse - a personal best of 9.90 - and South Africa's Akani Simbine with 9.89 are quick but not in Bolt's league while Yohan Blake's 9.69 came eight years ago.
