Sydney McLaughlin-Levrone broke the women’s 400m hurdles world record for the fifth time on June 30 after crossing the line in 50.65 seconds at the US Olympic trials in Eugene, Oregon.
The 24-year-old Olympic champion improved on her previous mark of 50.68sec set two years ago at the same Hayward Field track, to finish ahead of Anna Cockrell (52.64sec) as Jasmine Jones (52.77sec) took third.
McLaughlin-Levrone was in a state of disbelief after posting such a quick time.
“I’m just amazed, baffled and in shock,” she said. “There’s something really exciting about trying to figure out how to improve upon history.”
She exploded out of the blocks and took the lead immediately, gliding over each hurdle in a technically flawless performance.
Cockrell and Jones were left to battle for the last two spots on the podium, as McLaughlin-Levrone was all on her own around the final turn.
She was nearly two seconds clear of the rest of the field as she crossed the finish to thunderous applause from the crowd at the heart of American track.
She told reporters she did not have a time in mind heading into the event, focusing instead on her execution and technique.
“It’s just super encouraging just to see that… without expecting it. Knowing that there is more there,” she said.
She had only run in the event once this season before the 10-day US trials, which concluded on June 30, but showed no signs of rust as she jogged through the finish of her semi-final in a world-leading 52.48sec.
The only woman ever to run faster than 51 seconds in the event, she will bid to become the first woman to win back-to-back Olympic 400m hurdles titles in Paris.
“We’re in a great spot,” said McLaughlin-Levrone. “(The Olympics are) coming up fast but I know that this is a big confidence boost and also going to help us know what we have to fix.”
Dalilah Muhammad, the 2016 Rio champion, finished sixth in 54.27sec and said she simply ran out of time to get herself in tip-top shape for the trials.
