Mo Farah has made sporting history yet again after running to victory in the 5,000m in the Olympic stadium - his second gold medal in a single games.
Farah now joins an elite group of British runners, which includes Kelly Holmes, who can claim to have won the double.
The 29-year-old Londoner will be considered one of Britain's greatest ever track and field athletes.

He told the BBC: “It’s just unbelievable. I knew I just had to hold on to it and I got great support from the crowd.
"I just want to thank everyone who has supported me. It’s been a long journey, grafting and grafting.”
Farah's second gold comes just a week after he became the first Briton to ever win the 10,000m title.
Farah stuck to the back of the pack for the first few laps and despite a few breaks the pace remained slow.
But he burst through to the front of the group for the third lap to increase the pace.
On the bell for the final lap Farah held the lead, refusing to let anyone pass him. And into the final straight he looked strong and focused.

Despite a challenge he held the front and stormed across the line in first place.
After kissing the track he then performed the famous 'Mobot' celebration as 80,000 people cheered.
David Cameron tweeted: "Olympic legend and a true British hero. We can all be proud of his extraordinary achievement."
London 2012 chairman Lord Coe, a two-time Olympic 1500m champion, told the Press Association: "Mo Farah - a distance running great and arguably the best British runner of all time."
Farah is now one of only six men have managed to the 5,000m and 10,000m Olympic double.
The others are Hannes Kolehmainen, one of the original flying Finns, Czech Emil Zatopek, the Soviet Vladimir Kuts, Finland's Lasse Viren - managed the double in both 1972 and 1976 - and Ethioipia's Kenenisa Bekele.
Farah finished in a time of 13:41.66, in silver was Dejen Gebremeskel and in bronze was Thomas Pkemei Longosiwa.
