Sydney McLaughlin-Levrone smashed her own 400m hurdles world record on Sunday to book her place at the Paris Olympics in sensational style at the US trials in Eugene, Oregon. McLaughlin-Levrone obliterated her rivals to power home in an astonishing 50.65sec, bettering her previous best of 50.68, also set at Hayward Field, during the 2022 World Championships. McLaughlin-Levrone, the reigning Olympic champion, was out of the blocks quickly and then produced a devastating burst of speed down the stretch to finish ahead of Anna Cockrell (52.64sec) and Jasmine Jones (52.77sec).
