Ethiopia's Almaz Ayana put on a stunning display of front-running to win the women's 5,000 meters by more than 17 seconds at the IAAF World Championships on Sunday and deprive compatriot Genzebe Dibaba of an unprecedented double gold.

The 23-year-old powered away from Dibaba with four laps to go and led home an Ethiopian podium sweep in a championship-record time of 14 minutes, 26.83 seconds.

Dibaba, who was hoping to become the first woman to win both the 1,500 meters and 5,000 meters at the same world championships or Olympics, was pipped at the line by compatriot Senbere Teferi, who took silver in 14:44.07.
