Dibaba wins 10,000m title with final blast
Awesome display of speed lands champion her third world crown as others fall in her wake

Ethiopia's Tirunesh Dibaba bided her time before letting loose on the final lap with an awesome display of speed to complete a hat-trick of world championship 10,000 metres titles.
Olympic champion Dibaba, who is unbeaten in her 11 outings over the distance, won in 30:43.35.
Kenya's Gladys Cherono was second in 30:45.17 and fast-finishing Ethiopian Belaynesh Oljira pipped Emily Chebet for bronze in 30:46.98.
The half-full stadium got behind the petite runner known as the baby-faced destroyer and cheered her to the line but one person was not at Luzhniki to watch Dibaba's latest triumph.
"My sister [1,500m runner Genzebe Dibaba] did her heats this morning and wanted to watch me in the stadium tonight but I refused and told her to watch it in the hotel because she needs some rest," Dibaba said. "I have not decided if I will watch her here or if I will fly home."
