Jamaica Men’s 4x100m did not finish at the IAAF World Championships in London.

Bolt, left chasing the British and US anchor leg runners, comes to a stuttering, staggering halt halfway down the straight, dropping the baton before performing a forward somersault.

This was a challenge too far for him, and he crossed the finishing line for the last time, limping, with his team-mates beside him.

Meanwhile the British celebrations began in earnest after Nethaneel Mitchell-Blake had brought the baton home first in 37.47 ahead of the US last leg runner Christian Coleman, who tops this year’s world lists with 9.82. The US took silver in 37.52, with bronze going to Japan in 38.04.
