Ethiopia’s Tirunesh Dibaba defended her Olympic 10,000m title with a dominant display giving her rivals little chance on a stunning final lap.
Leading with 500m to go, the 26-year-old broke away from Kenya’s Sally Kipyego and Vivian Cheruiyot to win in 30 minutes 20.76 seconds.
Britain’s Jo Pavey and Julia Bleasdale smashed their personal bests as they finished seventh and eighth.
Pavey, 38, ran 30:53.20 with Bleasdale, 30, clocking 30:55.63.
Dibaba’s triumph was her third Olympic gold after winning both the 5,000m and 10,000m in Beijing – the first female athlete to do so.
