How Klaudia Kazimierska Became The Breakout 1500m Star Of 2026 & World Ultimate Champion

“The best athlete has short-term memory. After good races you push it away, and after bad races you just forget and move on.”

My guest for today’s episode is Klaudia Kazimierska — the World Ultimate champion at 1500 meters and one of the biggest breakthrough stories in track and field this year. She is 25 years old, a Nike pro, and trains under coach Jerry Schumacher in Eugene, Oregon. Her past month is the type of season most athletes would dream of.

Here is how September went for Klaudia. She broke the Polish national record early in the month at the Silesia Diamond League. Then she went to Brussels and won the Diamond League Final in 3:54.05 — a world lead, a meet record, and a Polish record again all in the same race. Then she came back a week later and won the World Ultimate Championship 1500 meter final. Then she capped her season in London with another victory over Hunter Bell. In those last three races, she earned $275,000 in prize money.

In this one, we go back to Poland, where she started running once a week at eleven years old because her dad knew the coach, ran 4:07 at nineteen and thought the Tokyo Olympics were right around the corner, then went backward. In 2021, frustrated and looking for something new, she started the paperwork to transfer to Oregon — a process complicated enough that it took a year. She’s made the Olympic and World Championship finals in the last two years, but 2026 was really the breakthrough. Brussels was the first time she put herself in a position to win. Then Budapest was the second.

We discuss:

– The season that still hasn’t fully settled in highlighted by three wins in three weeks — Diamond League final (Brussels), World Ultimate Championships (Budapest), Athlos London. Total prize earnings: approximately $275,000.

– Growing up in Poland

– Representing Poland at sixteen — and who else was there

– The road to the University of Oregon

– The language barrier and the fear of not being herself

– The training difference — Poland vs. Eugene

– The four-year plateau at 4:07

– The Paris Olympic final — and why she cried on a day she ran a PB

– What nobody knew about the 2025 NCAA Outdoor Championships

– The torn hip labrum that almost ended 2025 before it started

– The Tokyo World Championships and the first real glimpse of her kick

– Pre-Classic as the tactical lesson that made Brussels possible

– Brussels Diamond League Final— the shadow on the home straight: 3:54, the world lead.

– Budapest — the gear shift, the last 50 meters, and knowing everyone else was hurting too.

– London — finding the inside rail
