Mo Farah won the 5,000 meters to complete an Olympic distance double for Britain on Saturday night.

Backed by a boistrous, capacity crowd at 80,000-seat Olympic Stadium, Farah surged ahead late and held on to win in 13 minutes, 41.66 seconds. He still had the energy to do a few playful situps on the track before he grabbed a flag for the real celebrations.

Dejen Gebremeskel of Ethiopia won silver in 13:41.98, while Thomas Longosiwa of Kenya took bronze in 13:42.36.

The Somali-born Farah won the 10,000 meters on Britain's "Super Saturday" last weekend, the same night Jess Ennis won the heptathlon and Greg Rutherford the long jump.

Washington State University alumnus Bernard Lagat finished fourth.
