American hurdler Masai Russell set a new world record in the women’s 100-meter hurdles, clocking 12.09 seconds at the Diamond League meeting in Zurich on Thursday night, according to official race results and reports from Franceinfo.fr.
Masai Russell Breaks World Record in Zurich
Fresh off her gold medal performance at the Paris Olympic Games, Masai Russell etched her name into the athletics record books on the Letzigrund track in Zurich. Racing into a zero-wind condition, the American sprint star crossed the finish line in 12.09 seconds. The performance shattered the previous world record of 12.12 seconds, which had been held by Nigeria’s Tobi Amusan since the 2022 World Championships in Eugene, Oregon.
According to trackside reporting from Franceinfo.fr, Russell improved the global standard by three hundredths of a second. The remarkable run came during a swift evening of hurdle racing in Switzerland, unfolding moments after Alison dos Santos established a world record in the 400-meter hurdles.
A Heavyweight Podium on the Letzigrund Track
The elite 100-meter hurdles final featured a high-caliber field that pushed the pace from the blocks. Tobi Amusan finished second behind Russell, clocking a season-best time of 12.23 seconds. The Dutch hurdler Nadine Visser rounded out the podium places, taking third with a time of 12.34 seconds.

For Russell, the world record serves as the crowning achievement of a stellar championship cycle that began with her Olympic triumph in Paris during the summer of 2024. The Zurich Diamond League meeting once again proved to be a fast track for global elite sprinters looking to capitalize on late-season form.
