Mo Farah wins 5,000m World Championship gold in Beijing

Great Britain's Mo Farah completed a historic 'triple-double' by winning 5,000m gold at the World Championships.

Farah adds to the 10,000m gold won earlier in the championships, as well as the 5,000m and 10,000m double at the 2012 Olympics and 2013 World Championships.

5 live athletics correspondent Mike Costello commentates on the closing 400m of the race.

The Briton stayed on the shoulder of Kenyan Caleb Ndiku, before sprinting clear of his 22-year-old opponent in the final 100m.

He crossed the line in 13 minutes 50.38 seconds, running his final lap in a fast 52.6secs.
