Ethiopia's Gudaf Tsegay ran the second-fastest women's indoor mile of all time at a meeting in Poland on Wednesday.
The 5,000m outdoor world champion was aiming to add the mile best mark to her 1,500m indoor world record set in 2021.
She missed out on beating compatriot Genzebe Dibaba's record of four minutes and 13.31 seconds, posting 4:16.16 in Torun.
Tsegay won 5,000m world gold in Eugene last year, 12 months after taking Olympic bronze in Tokyo.
Olympic and world championship silver medallist Keely Hodgkinson of Britain set the fastest indoor 800m time of the year by winning her race in 1:57.87.
