Mo Farah and Sifan Hassan broke world records for the farthest distance run in one hour on a track, a rarely contested event, at a largely empty stadium in Brussels on Friday.
Farah, a four-time Olympic champion racing on the track for the first time in three years, bettered Ethiopian legend Haile Gebrselassie‘s mark of 21,285 meters — or 13.2 miles — from 2007. The Brit surged past Belgian training partner Bashir Abdi with a minute left.
Hassan covered 18,930 meters — or 11.76 miles — running more than a full lap more than the previous women’s record.
