McLaughlin-Levrone breaks own 400m hurdles world record at U.S. track trials

Sydney McLaughlin-Levrone lowered her world record once again, running the 400-metre hurdles in 50.65 seconds Sunday to win the U.S. Olympic trials.

In only her fourth long hurdles race of the season, the 24-year-old defending Olympic champion cleared all 10 barriers with ease, then went on a dead sprint to the line to break the record for the fifth time. Four of those marks have now come on track at University of Oregon's Hayward Field.

She held her hand over her mouth and stared in amazement when she saw the time come up. The mark was .03 seconds better than her run at Hayward in the 2022 world championships.

"Honestly praise God," she said in televised remarks. "I'm just amazed, baffled and in shock."

McLaughlin-Levrone exploded out of the blocks and took the lead immediately, soaring over each hurdle in a technically flawless performance.

She was several metres clear of the rest of the field as she crossed the finish to thunderous applause from the crowd in the heart of American track, smiling in a subdued celebration as she punched her ticket to Paris.

Anna Cockrell (52.64) was second while Jasmine Jones (52.77) took third.
