How choosing 400m flat ahead of 400m hurdles has helped Sydney McLaughlin-Levrone grow?
Sydney McLaughlin-Levrone has opened up about how running the 400m flat has helped her grow as an athlete. She described the 400m as an event that requires more mental strength than the hurdles, although she admitted missing the 400m hurdles at times.
For the 2025 season, the American is experimenting with the flat 400m. Ahead of the World Athletics Championships 2025, she spoke to Olympics.com about the differences between the two events, stating:
“The 400 is just more of a mental game than the hurdles. You would think, you know, hurdling - the steps, [but] there's a lot more thinking involved [in the 400m flat]. I miss the hurdles a little bit when I'm running. But it's been a mental gain. And I think that's pushed me as an athlete to have to grow in ways that maybe I didn't think I needed to.”
Besides her feature at the Worlds, Sydney McLaughlin-Levrone also competed at the Prefontaine Classic, making her debut at the Diamond League meet, which she won with a time of 49.43s.
