Farah becomes only the seventh man to win the 5,000m and 10,000m in a single Olympics. See the finish here.
Here's the last 400 meters.
Farah jostles with a number of other runners before dominating the final sprint. Unfortunately, his training partner and American runner Galen Rupp is unable to maintain the pace that he sets at the beginning of the last lap, and he fails to place.
