Rio de Janeiro: Britain`s Mo Farah overcame a dramatic mid-race fall on Saturday to take a second straight Olympic 10,000m title and extend his remarkable record at global championships.
The 33-year-old produced a trademark surge over the last 100 metres to time 27min 05.17sec in the 25-lap race.
Kenyan Paul Tanui won silver in 27:05.64 with Ethiopian Tamirat Tola third in 27:06.26.
Farah tumbled in the 10th lap after being clipped by American training partner Galen Rupp.
But he brilliantly recovered to accumulate a second 10,000m title to add to the 5,000m gold he also won in London four years ago.
It was his eighth successive win in the 5,000 or 10,000m at a world championships or Olympics since 2011, when Ibrahim Jeilan beat him over 10,000m in the Daegu world championships.
Farah has also notched up the European double, twice, in 2010 and 2014 to become one of the best middle distance runners of all time.
The 34 runners at the Olympic Stadium went through the first five laps at a steady pace, Farah working his way to the front after at first coasting at the back of the pack.
Ethiopian pair Tola and Yigrem Demelash immediately responded, Farah falling in with Rupp and exchanging a few words with his training partner under Oregon-based Alberto Salazar.
But there was drama to come, Farah taking a tumble during the 10th lap after being clipped by Rupp.
The Briton recovered quickly and flashed the American a thumbs-up as he refound his rhythm behind Tola, Tanui and his teammate Geoffrey Kamworor.
At the halfway mark, the field began to break up, the Kenyan duo taking up the front running. Team tactics then showed through, the third Kenyan, Bedan Karoki Muchiri, accelerating to the front.
His compatriots swept along with him, Farah looking comfortable in fourth as the pack slowed after the latest surge.
Demelash moved past Farah with six laps to run, another increase in the pace of the leading pack proving tough for anyone out of the top 10.
Farah, a regular competitor over 1500m to improve his speed work, led with two laps to run, holding off Tanui on his shoulder, Rupp behind him.
The Briton was passed by Tanui after going through the bell, but Farah held his nerve as a grimacing Tanui faded to time 55.37sec for the final lap.
