Mo Farah made it a golden athletics hat-trick for Great Britain at the Olympic Stadium.
In a stunning display of tenacity, talent and speed he beat Kenenisa Bekele, the Ethiopian 5,000m and 10,000m World and Olympic record holder, to win the Olympic 10,000m title.
His wife Tania, who is pregnant with twins, and daughter Rihanna came on to congratulate him on the track. Farah looked stunned but delighted as the crowd roared.
The packed stadium was already buzzing from Jessica Ennis's gold in the heptathlon and a surprise victory from Greg Rutherford in the long jump at the Olympic Stadium.
And Farah then rounded off an astonishing three triumphs in the space of 45 minutes with a blistering last lap in the 10,000m, completing it in 53 seconds to take gold ahead of American training partner Galen Rupp.
World 5,000m champion Farah had thought his race would not come down to the last lap as his rivals feared his sprinting speed, but in the end that was what happened and Farah hit the front at the bell to time his finish to perfection.
