Masai Russell announces attack on 12-second barrier after world record
Olympic champion Masai Russell arrives in Brussels as the new world record holder in the 100 metres hurdles and the leading favourite for the title at the Diamond League Final. Just one week after running 12.09 seconds in Zürich, the American says she feels even better than she did at the time of her record-breaking race and openly discusses a goal that until recently sounded almost unattainable: becoming the first woman to complete the event in under 12 seconds.
On Saturday, September 5, 2026, the King Baudouin Stadium in Brussels will be the stage for one of the most eagerly anticipated duels of the Wanda Diamond League Final. Russell will compete at the Allianz Memorial Van Damme for the first time as the world record holder, after running 12.09 seconds at the Weltklasse meeting in Zürich on August 27. According to official World Athletics data, she improved the previous record of 12.12, set by Nigeria's Tobi Amusan in 2022, by three hundredths of a second. The American athlete did so without the benefit of wind assistance: the official result from Zürich lists the wind at 0.0 metres per second. That is precisely why her assessment that there is room for an even faster race in Brussels carries additional weight, although every attempt to dip below 12 seconds depends on a range of technical, weather and competitive circumstances.
The record in Zürich changed the boundaries of the event
Russell defeated Amusan in Zürich, with Amusan finishing second in 12.23, while Dutch athlete Nadine Visser was third in 12.34. World Athletics marked the American's result as a world record subject to the usual official ratification process, while the organisers of Weltklasse Zürich stated that her race also produced a meeting record and a Diamond League record. It was the high point of a season in which Russell demonstrated almost race after race that she is currently the fastest hurdler in the world. According to the current World Athletics rankings, she leads the 100 metres hurdles, and in 2026, before Zürich, she had already run 12.14 in Xiamen, 12.20 in Monaco, 12.24 in Eugene, 12.25 in Shaoxing and 12.27 in Lausanne. Such a series of results shows that the record did not come as an isolated flash, but as a continuation of an exceptionally consistent season.
It is particularly significant that Russell ran in Zürich without measurable wind assistance. Ahead of the final in Brussels, she explained that this is precisely why she believes the 12-second barrier is not beyond reach. The Memorial Van Damme organisers relayed her assessment that a favourable legal wind, a good temperature and the energy of the stadium could create the conditions for an even faster race. In another appearance before journalists in Brussels, she also said that she feels in even better shape than she did a week earlier. This does not mean that a new record is certain, but it shows how quickly the psychological boundary of the event has shifted: after 12.09, the discussion is no longer only about whether the record can be improved further, but about when a result beginning with 11 might appear for the first time.
From Amusan's 12.12 to Russell's 12.09
The progression of the world record over recent decades shows how hard every hundredth of a second is to gain in the 100 metres hurdles. Kendra Harrison ran 12.20 in London in 2016, breaking the long-standing record of 12.21 set by Bulgaria's Yordanka Donkova in 1988. Six years later, Tobi Amusan lowered the mark to 12.12 in the semifinal of the World Championships in Eugene with a legal +0.9 metres per second wind. In the final later that same day, she ran an even faster 12.06, but with a wind of +2.5 metres per second, so under the rules that result could not be recognised as a world record. World Athletics subsequently officially ratified her 12.12, and that record remained at the top until Russell's race in Zürich.
Russell has now moved the official mark another three hundredths lower and opened a question that is being asked increasingly often in elite athletics: how close is the first legal result under 12 seconds? The difference between 12.09 and 11.99 is ten hundredths of a second, which in a sprint featuring ten hurdles represents a major, but not unimaginable, leap. Over that distance, the result depends not only on maximum speed, but also on the reaction at the start, rhythm between the barriers, technique over each hurdle and the ability to maintain form in the closing metres. One mistake can cost several hundredths, while an almost perfectly executed race, under ideal conditions, can create room for a historic result. Russell's consistency throughout 2026 is precisely why her announcement can no longer be viewed as mere ambition.
The Diamond League title matters more to her than the number itself
Although attention has naturally focused on a possible attack on 12 seconds, Russell is emphasising in Brussels that winning the trophy is more important to her than chasing a time for the sake of a time. According to a statement published by the final's organiser, the 26-year-old American says she wants to become a legend of the sport and that such status is built not only through records but also through titles. In 2026 she has won six Diamond League meetings, and organisers state that her winning times ranged from 12.09 to 12.27. The final in Brussels therefore offers her an opportunity to win her first overall Wanda Diamond League title, which would add another major trophy to her Olympic gold from Paris.
Russell has been the Olympic champion since 2024, when she won the final in Paris in 12.33 seconds. According to the official World Athletics results, France's Cyréna Samba-Mayela finished only one hundredth behind her, while defending Olympic champion Jasmine Camacho-Quinn was third in 12.36. That victory demonstrated Russell's ability to win a race under the greatest possible pressure, even when the time is nowhere near her personal or the world record. A year later, at the 2025 World Championships in Tokyo, she missed out on a medal and finished fourth in 12.44, behind Ditaji Kambundji, Amusan and Grace Stark. It was precisely after that championship that her 2026 season gained additional significance: instead of occasional top-level performances, she began stringing together victories and times from the very highest reaches of the event's history.
Amusan back on the same track
Brussels will not be a solo race against the clock. Tobi Amusan, the woman whose record Russell broke, has also been confirmed for the final and showed in Zürich that she is in good form by running a season's best of 12.23. Their renewed meeting just nine days after the record-breaking race gives the final a special competitive dimension. Russell is currently the clear favourite based on her 2026 results, but the 100 metres hurdles is an event in which the smallest technical error can change the order. Alongside Amusan, Nadine Visser is also among the leading names of the season, having confirmed in Zürich with 12.34 that she can remain in touch with the best.
For Russell, therefore, the first task is victory, and only then the time. In statements after Zürich, she repeatedly said that the job is not finished and that she no longer wants to run exceptionally fast without the trophy that turns such form into a title. That approach explains why Brussels is important even independently of a new record. The Diamond League Final brings not only another race against the strongest rivals, but also final confirmation of dominance across the season in a series that in 2026 consists of 15 stops, with the last one being a two-day final on September 4 and 5 in the Belgian capital. A total of 32 discipline winners will be decided in Brussels, 16 in the men's and 16 in the women's competition.
Two new world record holders arrive in Brussels from Zürich
Russell is not the only star of the final arriving in Brussels with a world record achieved in Zürich. Less than 40 minutes before her 12.09, Brazil's Alison dos Santos ran 45.80 in the 400 metres hurdles. According to World Athletics, he improved Karsten Warholm's record of 45.94, set in the Olympic final in Tokyo in 2021, by 14 hundredths of a second. Dos Santos also convincingly defeated Warholm himself in Zürich, with Warholm finishing in 46.69. The Memorial Van Damme organisers therefore present Saturday's programme as a rare opportunity for the audience to see, on the same evening, two world record holders who set their best performances at the same meeting only a few days earlier.
Dos Santos will compete in the 400 metres hurdles in Brussels, while Russell will pursue the title in the 100 metres hurdles. In its preview of the second day of the final, World Athletics highlights the two of them as the main stars of the programme. The Brazilian enters the season finale with an enormous performance advantage over most of his competitors, while Russell has shown exceptional consistency throughout 2026, ranging from low 12.2 performances to the world record. Their joint arrival further increases the significance of the 50th edition of the Allianz Memorial Van Damme, the traditional athletics meeting that this year once again serves as the Diamond League Final.
Brussels is a major goal, but not the last of the season
Russell's statement that the job is not finished also refers to what comes after Brussels. Just six days after the Diamond League Final, the inaugural World Athletics Ultimate Championship begins in Budapest, a new global competition that will be held from September 11 to 13. World Athletics states that Olympic champions, world champions, Diamond League winners and the highest-ranked athletes of the season will gather there. Russell has already secured her place as the reigning Olympic champion in the 100 metres hurdles. The final of the women's sprint hurdles is scheduled for the first day of the competition, September 11.
Such a schedule means that within just two weeks of the world record, the American will have two races that can further define her season. Brussels offers her the Diamond League trophy, while Budapest offers another global title in an entirely new format. World Athletics has announced a prize fund of 10 million US dollars for the Ultimate Championship, the largest in the history of athletics, with individual event winners receiving 150,000 dollars each. For Russell, however, the message from Brussels remains athletically simple: she wants to win titles while continuing to push the boundaries of her event. The world record of 12.09 is now the starting point, not the end of the process.
The 12-second barrier is no longer an abstract idea
Ahead of Saturday's race, the greatest attention will be focused on the scoreboard after the final hurdle. If Russell repeats her level from Zürich, the battle for victory alone will already be worth a world-class performance. If the start, rhythm, technical execution and legal wind assistance all come together, the conversation about a result under 12 seconds will become even more concrete. The history of the event shows that records often move in small steps: ten years passed from Harrison's 12.20 through Amusan's 12.12 to Russell's 12.09. Now the world's leading athlete has publicly said that she believes the next great psychological barrier can fall.
Still, the final in Brussels will not be reduced solely to the pursuit of one number. Russell arrives as the Olympic champion, the leading athlete in the world rankings and the winner of six Diamond League meetings this season, but opposite her will stand former world record holder Amusan and several other athletes capable of punishing even the smallest mistake. That is precisely why her decision to put the title ahead of the record makes competitive sense. If she wins, she will claim the first Diamond Trophy of her career; if she also improves her own 12.09, Brussels could become another stop in the history of the event. And if a time below 12.00 appears on the scoreboard, women's sprint hurdles will enter an entirely new era.
