The American Olympic champion Dalilah Muhammad set a world record in women’s 400-meter hurdles at the American Championships in Des Moines, Iowa.
Dalilah Muhammad finished the track in 52.20, 14 hundredths of a second faster than the 52.34 that Russian Yuliya Pechonkina put down in 2003. In the American trials, the 29-year-old Olympic champion made it on the wet slopes of the Drake stage of Sydney McLaughlin (52.88), a 19-year-old emerging talent in the discipline.
At the Diamond League of Oslo, McLaughlin beat its rival last month in the final meters. Yesterday during the trials, she was unable to make up for her deficit on Muhammad in the last straight line. Third place went to Ashley Spencer in 53.11.
