Masai Russell ran 12.09 at the Letzigrund on Thursday night to take the 100m hurdles world record off Tobi Amusan, and she did it with a wind gauge reading 0.0.
No help. No tailwind. Three hundredths off Tobi Amusan’s 12.12 from the 2022 Worlds semi in Eugene.
The Olympic champion crossed first, Amusan came home second in a season’s best 12.23, and European champion Nadine Visser took third in 12.34. Home favourite Ditaji Kambundji, the reigning world champion, finished seventh in 12.82 in front of her own crowd.
Weltklasse Zürich 2026 — women’s 100m hurdles
- 🥇 Masai Russell (USA) — 12.09 WR
- 🥈 Tobi Amusan (NGR) — 12.23 SB
- 🥉 Nadine Visser (NED) — 12.34 SB
- 7th Ditaji Kambundji (SUI) — 12.82
It is also the fastest 100m hurdles ever run at this meeting and in the Diamond League, comfortably inside the 12.29 Amusan ran in Zurich four years ago.
The build-up to this had been running all season. Russell went to Zurich unbeaten in 2026 and had already clocked 12.14 in Xiamen in May — the second-fastest time in history at that point, and enough to put the record under permanent threat. Everyone in the event knew what was coming. The only question was where.
“A world record with zero wind is the scariest kind. She didn’t get gifted anything — she just went and took it! BRAVO!!” – 🎙️Jay
What makes the 100m hurdles world record land differently is what Russell already had in the bank. She is the first woman to hold the Olympic title and the world record in the event at the same time since Yordanka Donkova, the Bulgarian who won gold in 1988 and kept the record until Keni Harrison broke it in 2016. Russell and Harrison are the only American women to have held the mark at all.
That is the company she has walked into, and she is 26.
Masai Russell:
“I’m still processing it. I’ve been chasing it and the world’s been talking about it, so just to finally do it, it’s like, all right, I can breathe a little bit. Not all the way, but partially.”
The wind reading is the detail she kept coming back to afterwards, and for good reason. A legal tailwind in this event can sit anywhere up to 2.0m/sec. Russell got none of it.
Masai Russell:
“It’s crazy because the race had no wind at all. If we get a 1.9 wind behind my back, that could have been a sub-12 race. I do think it is possible.”
No woman has ever run under 12 seconds over the barriers legally. Russell is now the closest anyone has been, and she is saying it out loud rather than dancing around it.
Masai Russell:
“Everything that I’ve said that I wanted to do has come into fruition, so why not say I think I can be the first one to run sub-12?”
The Zurich crowd got two of these in one evening. Less than forty minutes before Russell’s run, Alison dos Santos clocked 45.80 to break the men’s 400m hurdles world record, meaning the Letzigrund produced two world records inside an hour on the same programme. Both marks now go through World Athletics’ standard ratification process.
Amusan’s four-year hold on the event is over, and she went out at the highest level she has produced this season rather than fading anonymously. A 12.23 is not a runner in decline. She simply ran into someone in the best form of her life.
Russell’s own progression tells the story of how quickly this arrived. She took the Olympic title in Paris in 12.33, then ran 12.17 for an American record in May 2025, then 12.14 in May 2026. Each step was small on paper. Cumulatively they turned an Olympic champion into a record holder.
There is also the reminder that this event punishes anyone who assumes anything. Russell finished fourth at the World Championships in Tokyo last year in 12.44, a year on from Olympic gold. Barrier racing does not care about form lines. That is what makes a full season unbeaten, capped by this, worth stopping for.
The season is not finished either. The Diamond League concludes across two days in Brussels on 4–5 September, and Russell arrives there as the fastest woman in the history of the event.
The record is hers. The number she actually wants still starts with an eleven.
