Beijing (AFP) - Ethiopia's Almaz Ayana trumped double world title-hunting teammate Genzebe Dibaba for victory in the women's 5000m on Sunday.
Ayana clocked a championship record of 14min 26.83sec, with Senbere Teferi, in 14:44.07, pipping Dibaba by 0.07sec on the line for an Ethiopian clean sweep of the podium places.
Dibaba had already won the 1500m, but Ayana's pace over the last five laps proved too rapid in her quest for a double.
