When Does Sydney McLaughlin-Levrone Run at the 2025 World Championships? Her Full 400m Schedule Revealed!
The 2025 World Track and Field Championships in Tokyo are underway, and all eyes are on Sydney McLaughlin-Levrone. Known as the queen of the 400m hurdles, the Olympic and world champion is stepping into bold new territory: the flat 400 metres.
After clocking a blistering 48.90 seconds at the U.S. Championships earlier this summer, McLaughlin-Levrone is ready to test herself against the world’s best in an event she’s never contested on this stage. Fans everywhere want to know one thing: When will she run?
Sydney McLaughlin-Levrone’s 400m Schedule (Tokyo 2025)
All times are listed in Eastern Time (ET). (Tokyo is 13 hours ahead of ET.)
Stage Date Time (ET) Event
Heats Sunday, Sept. 14 6:25 AM ET Women’s 400m Heats — Sydney’s first test in the flat 400m
Semifinals Tuesday, Sept. 16 8:05 AM ET Women’s 400m Semifinals — if she advances
Final Thursday, Sept. 18 9:24 AM ET Women’s 400m Final — the showdown for gold
Why This Race Matters
History in the making: McLaughlin-Levrone is already a two-time world record breaker in the hurdles. Now she’s chasing greatness in the flat 400m a shift fans have long anticipated.
A comeback moment: In 2023, she qualified for the flat 400m but withdrew due to injury. This year, she finally takes the stage healthy and in peak form.
A stacked field: Her 48.90s season best places her among the fastest women in the world this year, meaning she’s a real threat to medal and maybe even flirt with history again.
What to Watch For
This is more than just another race. It’s a career-defining experiment. Can the reigning queen of the hurdles conquer the open 400? Will her legendary finishing strength carry her past the flat-race specialists?
One thing’s certain: when Sydney steps on the track, the world will be watching.
