American hurdler Masai Russell on Thursday broke Nigerian sprint hurdler Tobi Amusan’s four-year-old world record in the women’s 100m hurdles, clocking 12.09 seconds at the Zurich Diamond League.
World Athletics, in its report on the meeting, said the Olympic champion produced a “flawless run” over the barriers to take 0.03 seconds off Amusan’s previous world record of 12.12 seconds.
The governing body added that Nigeria’s Amusan finished second in a season’s best of 12.23 seconds, while European champion Nadine Visser of the Netherlands placed third in 12.34 seconds.
The performance made Russell the new world record holder, American record holder and the fastest woman ever recorded in the 100m hurdles.
World Athletics’ statistics page lists Russell’s 12.09 as the latest world record in the event, achieved at the Letzigrund stadium in Zurich on August 27, 2026.
