The world’s top distance runner is at his stunning best as he adds the 5000m title to the 10,000m he won last weekend

Britain’s Mo Farah became the first person to complete three consecutive 5000m-10,000m doubles at world level, claiming his fifth World Championships title.

Seven days after winning the 10,000m, he disposed of the field with his usual incredible finishing pace after a painfully slow race.

Kenya’s Caleb Ndiku was his only challenger over the final lap, leading the Brit before he was passed in the finishing straight.

Farah’s time of 13:50.38 was the slowest winning mark in the Worlds or Olympics since 1968 as he finished more than a second in front of Ndiku. Ethiopia’s Hagos Gebrhiwet took bronze. Britain’s Tom Farrell, who led for much of the first two kilometres, finished last in 14:08.87.

In contrast to the quick 10,000m, the 5000m went out at a relative snail’s pace. The opening kilometres were 3:02 and 2:56 and 3000m was passed in 8:47.28, which was slower than the British women’s No.1 this year has run. Farah, who had been accidentally tripped in the 10,000m final and 5000m qualifying, spent much of the time jogging at the back at the field and keeping out of trouble.

The fourth kilometre was quicker at 2:44 but the race did not get going until 800m to go when Ndiku came past Farah.

The Brit was content to let Ndiku lead and the Kenyan even pulled away marginally as ran 26.08 for the penultimate 200m. However, it was too quick and Farah blitzed past with around 80 metres remaining, completing a 54.24-second lap.

His last 800m had been a sensational 1:49.3 and his last 600m was 1:20.5 – quicker than the corresponding split of David Rudisha as he won the two-lap final. His last kilometre was 2:19 and his last 600m was 2:19.2 – just eight seconds outside the world best.

Britain’s most successful athlete of all time is now among a small handful of athletes to have won as many as five world titles in individual events and he also won both events at the London 2012 Olympics.

He has not been beaten in a championships since picking up silver in the 10,000m at the 2011 World Championships.

Farah said afterwards: “Tonight I had to dig deep as you could see it came down to the last 100m.

“I kind of felt a bit tired, going through the rounds and to come back again. It is difficult as everybody has got great speed and there are a lot of guys who are capable of winning. They went for it.

“The important thing is to win the race and I did that.”
