Meseret Defar beat her own world record by almost 12 seconds in the women's 2-mile at the Van Damme Memorial meet.
The Ethiopian finished in 8 minutes, 58.58 seconds.
Defar already set world records in the 5,000 and the 3,000 indoor early in the season before improving the world best twice in the rarely run 2-mile event.
Defar shaved 11.89 seconds off the 9:10.47 mark she set in Carson, California, earlier this year. She also became 5,000 world champion at the world championships in Osaka, Japan last month.
