American track sensation Sydney McLaughlin-Levrone created history by running the fastest women’s 400 metres in 40 years, clocking 47.78 seconds to win world championship gold in Tokyo on Thursday, 18 September 2025. This victory marked her successful transition from the 400m hurdles, where she is already a two-time Olympic and one-time world champion, to the flat 400m.

Significance of the Achievement

- Her run was also a new American record, surpassing her own 48.29s from the semifinals.
