Mo Farah of Britain became the first runner in 40 years to win back-to-back long-distance doubles at the Olympics by taking gold in the men's 5,000 meters.
Farah already won the 10,000 meters at the Rio de Janeiro Games to go along with his two gold medals from the same events in London four years ago.
The last man to win both distance races in consecutive Olympics was Finnish great Lasse Viren at the 1972 Munich and 1976 Montreal Games.
Farah won with 13:3.30. Paul Chelimo of the United States took silver and Hagos Gebrhiwet of Ethiopia got bronze.

Washington State legend Bernard Lagat placed fifth, but for a short time was a bronze medalist. Chelimo was initially disqualified for stepping out of bounds, along with Canadian Mohammed Ahmed and Ethiopian Muktar Edris. However, Chelimo and Ahmed appealed, and they were reinstated, pushing Lagat out of the top three.
Lagat finished with a time of 13:06.78.

Puyallup's Hassan Mead placed 11th with a time of 13:09.81.
