Three years ago, she lowered the limit below 52 seconds for the first time, and then she broke her own record four more times - including tonight's all-time race in Paris.
Sidni McLaughlin-Levron "blown away" the competition and it seemed powerful Femke Bol in the final of the 400-meter hurdle race at the Olympic Games - to defend the gold from Tokyo, for a new world record of 50,37 seconds.
The question of the winner of this race was solved by the unreal girl from New Jersey long before the finish, and then she fought with herself, with the record (50,65) she set a little over a month ago in Eugene.
Much later, her compatriot Ana Kokren (51,87) and Femke Bol (52,15) crossed the finish line, who this time had to settle for a bronze medal.
The fact that before her appearance, the world record was 52,16 and was teased by Dalila Muhamed, is perhaps the best indication of what an endeavor and what kind of athlete she is.
