Olympic Trials in June, when McLaughlin took down Muhammad, who was recovering from injuries and COVID-19, and snatched Muhammad's world record.
McLaughlin overtook Muhammad in the final ten meters and won the gold medal, lowering her world record to 51.46.
Muhammad was second in 51.58, her fastest time ever, a time that would have been a world record on any other day.
Muhammad led the field through all ten hurdles; McLaughlin blasted through the second curve and trailed Muhammad by a stride through hurdles nine and ten.
Despite their ferocious battles on the track, McLaughlin and Muhammad are warm and complimentary off it, perhaps because they bring the best out of each other.This was the fourth championship final in which they faced off and set a new world record.
McLaughlin is now one of the new faces of American track and field, along with 19-year-old Athing Mu, who won gold in the 800-meter; Gabby Thomas, who took bronze in the 200-meter; and the silver medalist shot putter Raven Saunders.With the great Allyson Felix competing in her fifth and final Olympics, McLaughlin is one of the women who will carry the sport forward as the world championships come to Hayward Field in Oregon in 2022.
"In terms of what's possible, I don't think there is such thing as a true perfect race," McLaughlin said
