Usain Bolt leading the rela

Usain Bolt capped his double gold in the 100 and 200 metres with a third gold medal in the relay race at  the Beijing World Championships,  on a night when poor changeovers extinguished the 4×100 metres medal hopes of the United States and Great Britain.

Bolt anchored the Jamaican team of Nesta Carter, Asafa Powell and Nickel Ashmeade to victory in a world-leading 37.36 seconds.

A sloppy baton change between Tyson Gay and Mike Rodgers – sprinters who, like Justin Gatlin, have served doping bans – saw them disqualified in a race the British team did not even finish.

Richard Kilty, Danny Talbot, James Ellington and Chijindu Ujah had the potential to secure a podium spot, but once again a baton changeover proved their undoing.

Ellington and Ujah messed up the on the last leg – two years after the former’s changeover with the omitted Harry Aikines-Aryeetey saw bronze chalked off in Moscow

The British women fared much better 20 minutes earlier in their 4x100m final, although they too left without a medal.

Asha Philip, Dina Asher-Smith, Jodie Williams and Desiree Henry underlined their class with a wonderful display, producing a national record of 42.10secs.

It was an exciting display a year out from the Olympics and just seven hundredths of a second off bronze, won in a national record time by Trinidad and Tobago.

United States took silver behind a Jamaica team brought home by Shelly-Ann Fraser-Pryce in a championship record of 41.07s – the second quickest time of all-time.

In the 5000 metres race,  Britain’s Mo Farah achieved an unprecedented ‘triple double’ with victory.

The 32-year-old, who did the distance double of 5,000m and 10,000m titles at the London Olympics in 2012 and in Moscow in 2013 is the first man to then go onto defend his titles at another World Championships.

The Bird’s Nest stadium was a cacophony of noise as Farah overtook Caleb Ndiku round the final bend and put his foot on the gas to accelerate to his second World title in eight days, after winning 10,000m gold last Saturday.
