Klaudia Kazimierska sets Polish 1500 m record and wins Diamond Trophy in Brussels

Victory in Brussels and world-leading time

Polish runner Klaudia Kazimierska won the women's 1500 metres at the Diamond League final in Brussels on Saturday, clocking a world-leading time of 3:54.05. The 25-year-old athlete broke the meeting record of 3:54.75 set by Faith Kipyegon in 2024. Her performance also improved her own Polish national record of 3:55.59, which she had established on 23 August at the Kamila Skolimowska Memorial in Chorzów. Kenya's world silver medallist Dorcus Ewoi finished in second place with a time of 3:54.72, narrowly edging Australia's Jessica Hull, who clocked 3:54.73. European champion Georgia Hunter Bell finished fourth in 3:56.40.

Tactical execution and final surge

Kazimierska maintained a conservative position during the opening stages, staying toward the rear of the pack while monitoring competitors including Lorea Ibarzabal, Hull, and Hunter Bell. She held her rhythm without pushing prematurely toward the front. With approximately 200 metres remaining, Kazimierska initiated a decisive move between opponents and surged into the lead. She maintained her pace on the final straight, widening the gap as the rest of the field contested the remaining podium positions. Kazimierska addressed her preparation and performance in comments cited by Athletics News.

The result surprised me as much as everyone else. I worked on many small elements and they seem to have aligned perfectly. This is the fruit of consistent work. I think more success will follow because I am still chasing victories and titles. This race came at the ideal moment. After the European Championships, I wanted to reach a second peak of form.

Continental rankings and points record

The performance lifted Kazimierska from fifth place to first on the 2026 global leaderboard and represents the sixth-fastest 1500 metres time in European history. She became the second European runner under 26 years old to break the 3:55 barrier, joining Romania's Paula Ivan, who ran 3:53.96 at the 1988 Seoul Olympics. According to Athletics News, the mark earned 1254 points on the international scoring tables, surpassing Natalia Bukowiecka's 400 metres record of 48.90 seconds (1250 points) as the highest-scoring running performance in Polish history. Anita Włodarczyk retains the overall Polish points record with 1303 points from her 82.98-metre hammer throw world record set in 2016 at PGE Narodowy.

Diamond Trophy and season milestones

The victory earned Kazimierska the Diamond Trophy, higher prize money, and a wild card for the upcoming World Athletics Championships in Beijing. She became the third Polish athlete to claim a Diamond Trophy, following four-time discus winner Piotr Małachowski (2010, 2014, 2015, 2016) and high jumper Mateusz Kołodziejski, who secured his victory on Friday. Kazimierska's 2026 campaign previously featured double gold in the 800 and 1500 metres at the Polish championships in Białystok, a national mile record of 4:17.90 in Eugene, a 1500 metres silver medal at the European Championships in Birmingham, and a second-place finish in Rome. In the men's javelin in Brussels, Dawid Wegner took second place with a personal best of 87.47 metres, behind Sri Lanka's Rumesh Tharanga Pathirage with 89.04 metres, while Keshorn Walcott finished third.
