The Ethiopian middle-distance runner clocked her record-breaking time at the World Athletics Indoor Tour meeting in Lievin on 19 February 2020, setting her fourth PB within three weeks.

The race was won by her compatriot, world bronze medallist Gudaf Tsegay, but Hailu put up a good fight.

Lemlem Hailu’s world U20 indoor 1500m record of 4:01.57, set last year, has been ratified.

Hailu, the 2017 world U18 champion, now sits at 18th on the senior world indoor all-time list.
