Her time of five minutes 23.75 seconds sliced almost seven seconds off the previous indoor world record of 5:30.53 set by Romania’s Gabriela Szabo in 1998.
The IAAF, athletics’ world governing body, said although the 2,000m is not an official indoor world record event, Dibaba’s performance was “an outright world record” as it was faster than the outdoor mark of 5:25.36 set by Ireland’s Sonia O’Sullivan.
The 25-year-old Dibaba, a three-time world indoor champion, now owns the fastest recorded times indoors for the 1500m, mile, 2,000m, 3,000m, two miles and 5,000m as well as the outdoor 1500m world record.
