Sydney McLaughlin-Levrone

Four consecutive world records in the 400m hurdles — the most technically improving event in modern athletics.

Sydney McLaughlin-Levrone was born in New Brunswick, New Jersey in 2000. She has broken the 400-metre hurdles world record four times since 2021 — currently holding the record at 51.29 seconds set at the Paris 2024 Olympics. She won Olympic gold at Tokyo 2021 and Paris 2024. She has won two World Championship titles. Her technical progression — each world record involving a specific refinement of her hurdling technique — has made her the subject of more biomechanical analysis than any other track athlete of her era. Her collision course rivalry with Dalilah Muhammad produced the most watched individual event in women's track athletics across multiple championships. She became the first woman to break 52 seconds in the 400 hurdles, then 51 seconds. At 24 she has already produced the most decorated individual 400 hurdles career by any woman. She is also an elite flat 400-metre runner and the combination of both disciplines across her career suggests records that could stand for a generation.
