Mo Farah and Sifan Hassan broke world records in the rarely run one-hour race Friday at the Memorial Van Damme meeting.Farah, the four-time Olympic champion, ran 21.33 kilometers (13.254 miles), topping Haile Gebrselassie's 2008 mark of 21.285 kilometers (13.226 miles).
Hassan of the Netherlands covered 18.930 kilometers (11.763 miles) to improve on the previous record of 18.517 kilometers (11.506 miles) set by Ethiopia's Dire Tune at the Ostrava Golden Spike meeting in 2008.
Hassan and marathon world-record-holder Brigid Kosgei of Kenya fought toe to toe at the King Baudouin Stadium, which was empty because of the coronavirus pandemic. Hassan accelerated in the final minute to leave Kosgei powerless in her slipstream.Reigning Olympic 1,500-meter champion Faith Kipyegon of Kenya failed in her bid to break the 1,000 meters record, crossing in 2 minutes, 29.92 seconds, shy of Svetlana Masterkova's 2:28.98 record set in the same stadium in 1996.
Kipyegon set the second-best time over the distance last month in Monaco, in 2:29:15. Following the sustained tempo of a pacemaker, she looked on track to set a new record but faded over the final 150 meters.The Associated Press contributed to this report.
