Rio Olympics 2016: Great Britain's Mo Farah wins 5,000m & 10,000m 'double double'

Great Britain's Mo Farah won his fourth Olympic gold medal as he became only the second man in history to retain the 5,000m and 10,000m titles.

The 33-year-old triumphed in the 5,000m final in Rio to extend his tally as Britain's most successful Olympic track and field athlete of all time.

Farah won in 13 minutes 3.30 seconds as Scot Andrew Butchart finished sixth.

"It shows I didn't just fluke it in London. To do it again is incredible. I can't believe it," said Farah.

Farah's was Britain's 27th gold in Rio and their 65th medal, matching the haul at London 2012.

They surpassed that tally when the women's 4x400m relay team won bronze in the penultimate track event of the Games.

More history for Mo

Farah cemented his place as one of Britain's greatest athletes with his double success four years ago, but repeating the feat makes him the world's most successful distance runner in terms of major medals.

"My legs were a bit tired after the 10k. I don't now how I recovered," he told BBC Sport.

"I wished for just one medal as a junior. It has been a long journey but if you dream of something, have ambitions and are willing to work hard then you can get your dreams."

Somalia-born Londoner Farah is now a nine-time global champion, moving him above Ethiopian great Kenenisa Bekele.

He matched the feat of Finland's Lasse Viren, who completed the long-distance double at the Munich 1972 and Montreal 1976 Olympics.

Farah had already achieved the World Championships 'double double', successfully defending his 10,000m and 5,000m titles in Beijing last year.

Analysis

Brendan Foster, Olympic medallist and BBC athletics commentator:

"What a moment. What a fantastic performance. What a privilege to see this man collect a fourth Olympic medal in style. He did it the only way he knows how.

"Mo, you are a treasure. You are more than a national treasure. You are the greatest we have ever had and one of the greatest distance runners we have ever seen."

Michael Johnson, four-time Olympic medallist and BBC analyst:

"Everyone works hard, but it is also about working smart, finding the things that will really make those marginal gains, assessing and diagnosing what areas can improve.

"What else makes Mo special is his race intelligence and ability to show up on the day and deliver the performance he is capable of. He has done that time and time again."

Paula Radcliffe, women's marathon world record holder:

"Mo does not believe he will be beaten. He sees no reason why he can't be competitive in every race he competes in."

Denise Lewis, BBC Sport athletics expert:

"It has been a privilege to see how he has progressed from that junior athlete who did not quite make it to this amazing athlete. But the decisions he has made over the last few years, to move to America and do what is needed to achieve success, shows how absolutely committed he is."

Mike Costello, BBC athletics correspondent:

"For the first time out of all his finals I've covered I didn't think he was going to win. It is astonishing he still had something in reserve. He ran the last of his 50 laps in Rio in 52 seconds. That's incredible."
