In 4:12.33, Sifan Hassan of the Netherlands made history on Friday, breaking the women’s mile world record at Monaco’s Diamond League meet.
The previous record of 4:12.56 had been held by Russia’s Svetlana Masterkova since 1996.
Halfway through the race, Ethiopia’s Gudaf Tsegay trailed Hassan closely. However, during the last half-lap Hassan was all by herself, competing against the clock.
The 26-year-old finished five seconds faster than Britain’s Laura Weightman, who took second place.
Hassan ultimately shaved two seconds off of her national record of 4:14.71.
