Sydney McLaughlin-Levrone

Sydney McLaughlin-Levrone (née McLaughlin, born August 7, 1999) is an American hurdler and sprinter who competes in the 400 meters hurdles. She is the 2020 Tokyo Olympic champion with the Games record, and 2022 World champion with a world record time of 50.68 seconds. Setting four world records during 13 months, she was the first woman to break the 52-second (June 2021) and 51-second (July 2022) barriers in the 400 m hurdles. She won the silver medal at the 2019 World Championships. At all three competitions, she also took gold as part of a women's 4 × 400 m relay team.

As a 15-year-old, McLaughlin was the 2015 World youth champion. In 2016, she was the youngest athlete since 1980 to qualify for the U.S. Olympic track team, having placed third at the U.S. Olympic Trials, with the current world under-18 best of 54.15 seconds, then also the world U20 record. She holds the current world U20 record of 53.60 seconds, having achieved a junior personal best of 52.75 s (not ratified), with both marks set in 2018. Only two other women also broke the 52-second barrier and McLaughlin-Levrone is the only one who broke the 51-second barrier, leaving her with nearly one second advantage on the world all-time list, the largest current difference between the world record and the next best performer in said track event. She holds six out of the nine fastest times on this list. She was the 2019 Diamond League champion.

In 2022, McLaughlin-Levrone was voted World Athletics Female Athlete of the Year.
