Sydney McLaughlin again breaks own world record in winning first 400m hurdles title at world championships

EUGENE, Ore. — In the hurdles world before Sydney McLaughlin, it took years to shave fractions of seconds off records, and winning races didn’t always mean rewriting history.

This once-in-a-lifetime athlete is obliterating that mindset as quickly as she’s destroying the records she sets again and again.

For the fourth time in 13 months, the 22-year-old McLaughlin set the world record. On Friday, she ran the 400-meter hurdles at world championships in 50.68 seconds. She shattered her old mark by 0.73 seconds, a ridiculous number for a race of this distance and an amount of time that, in the world before McLaughlin, it had taken 33 years to trim.

“It’s unreal,” McLaughlin said in the postrace interview on the track.

She beat second-place finisher Femke Bol of the Netherlands by 1.59 seconds. McLaughlin’s main rival, Dalilah Muhammad, finished third in 53.13 seconds, a time that would’ve won the world title with ease a mere seven years ago.

And yet, as McLaughlin summed up her takeaways from the evening — an evening in which she delivered in a race she has turned into one of track’s must-see events — she was far from ready to declare she had run the perfect race.

“I haven’t had a chance to watch it, so I’ll have to do that and go back and talk to my coach,” McLaughlin said. “But I think there’s always things to improve on. I think we’re pushing the boundaries of the sport, especially in our event.”

After McLaughlin received her gold medal and listened to “The Star-Spangled Banner,” World Athletics president Sebastian Coe handed her a $100,000 check — the prize for breaking the record at worlds. This marked the fourth straight major race in which she’s bettered the mark.

On a clear, perfect, 72-degree night at Hayward Field, McLaughlin left Bol and Muhammad behind by the 150-meter mark. By the time the American reached the final curve, it was clear this would strictly be a race against the clock.

“It was crazy,” Bol said. “She was so far in front at the…
