Birmingham: Ethiopia's serial record-holder Genzebe Dibaba won a fourth consecutive world indoor title when she romped to victory in the 3,000m in Birmingham on Thursday.
In a memorable opening night of track and field for Russians cleared to compete as neutrals in the wake of the doping scandal that has engulfed their country, Danil Lysenko and the unbeatable Mariya Lasitskene took golds in the men and women's high jump competitions.
Dibaba came to Birmingham as double defending 3000m indoor champion and had also won the 1500m in Istanbul in 2012.
And the 27-year-old favourite made no mistake at the Arena Birmingham, streaking around the blue track for an unprecedented eighth Ethiopian victory in the last nine world indoor 3000m events, Kenya's Hellen Obiri the only blot back in 2012.
Obiri, the world outdoor 5,000m gold medallist who won silver over the distance in the Rio Olympics and also picked up 1500m bronze at the 2013 worlds in Moscow, could only finish fourth this time around.
British hopes rested with European indoor champion Laura Muir and Eilish McColgan, whose mother Liz won silver in 1989. It was eventually Muir who hung on for bronze, a first global medal.
Current world record holder for the 1500m (both indoor and outdoor), the indoor 2000m, the indoor 3000m, the indoor 5000m, the indoor mile, and the indoor two mile, Dibaba was happy to sit at the back as Muir took up the early front running.
