On an evening of stunning middle-distance performances at the Meeting Hauts-de-France Pas-de-Calais, Ethiopia’s Gudaf Tsegay produced the highlight by taking two seconds off the world indoor 1500m record*, winning at the World Athletics Indoor Tour Gold meeting in 3:53.09.
The world bronze medallist followed the swift early tempo as the pacemaker led the field through 400m (58.97) and exited just before 800m, which Tsegay passed in 2:05.94.
With three laps to go, Tsegay had a four-second lead over double European indoor champion Laura Muir but she showed no signs of slowing down, passing through 1000m in 2:37.36.
The clock read 2:52.9 with two laps to go and Tsegay maintained her pace with another lap just outside 30 seconds. She dug in for the final circuit and crossed the line in 3:53.09, taking more than two seconds off the world indoor record set by compatriot Genzebe Dibaba in Karlsruhe in 2014.
Muir finished second in a British indoor record of 3:59.58 with teammate Melissa Courtney-Bryant taking third in 4:04.79.
