What Did Masai Russell Do in Zurich?
At Weltklasse Zürich, Russell stormed to victory in the women's 100m hurdles in 12.09 seconds. The BBC reported it as the second world record of the night at the Letzigrund stadium, capping one of the most extraordinary evenings in recent track history.
Russell, 26, had been closing on the record throughout 2026. She ran 12.14 in Xiamen in May — at that point the second-fastest time ever recorded — and said she had been telling reporters all year that she would break the world mark. In Zurich, with the wind gauge reading a dead calm 0.0m/sec, she delivered.
Whose Record Did Russell Break?
Russell ended a reign that had stood since Tobi Amusan ran 12.12 in the semi-finals at the 2022 World Championships in Eugene. Amusan herself was in the Zurich field and took second place in a season's best 12.23, but could not match the American's pace.
European champion Nadine Visser finished third in 12.34, also a season's best. Reigning world champion Ditaji Kambundji, racing in front of a home crowd, placed seventh in 12.82. Russell's 12.09 also smashed the previous meeting record of 12.29, which Amusan had set in Zurich in 2022.
Why Does This World Record Matter?
For Russell, the run confirms a season-long trajectory from contender to outright world-beater. She is the Olympic champion, and this mark gives her undisputed ownership of the event's fastest legal time. Her time stands as both a Diamond League record and a meeting record at one of athletics' most prestigious one-day meetings.

What Happened Earlier on the Same Night?
Minutes before Russell's run, Brazil's Alison dos Santos broke Karsten Warholm's 400m hurdles world record at the same meeting — making Zurich 2026 a double world-record evening. Athletics Weekly described Russell's performance as one of the standout moments of an extraordinary night at Letzigrund, bookending an evening that will be remembered long after the stadium lights went out.
