Yeah. That happened. 400m HURDLE WORLD RECORD 51.90 for @sydneymclaughlin16 last night at the final day of the Olympic Trials. Her world record run put her ahead of former world record holder and 2019 World Champion @dalilahmuhammad_ who ran an impressive 52.42 after a season of hurdles (literally and metaphorically) Muhammad has set the World Record twice while running against McLaughlin, but McLaughlin is the first time a woman who has run under 52 seconds in the event. These two are certainly in contention to go 1-2 in Tokyo. Finishing not far behind in third was USC Hurdler @annacockrell making her first Olympic team in a lifetime best of 53.70. #TrackFieldTrials21 #TrackTown20
