In November 2024, I was diagnosed with acute leukemia. In March 2025, I received a bone marrow transplant from a donor in Poland. On August 30, 2026, I was back on the start line in Tábor.

Who I am
A decathlete from Tábor.
I’ve done track and field since I was little. Until I was fourteen, I tried a bit of everything and didn’t take any of it too seriously. Then at fifteen I shot up and improved a lot within a single year. That’s when I fell for elite sport completely and started training for real.
I was good at several events, so my coaches pointed me toward the all-around events from the start. I won my first national medal in the long jump in the winter of 2021, at sixteen. Then things took off: 10 medals at the Czech Championships across age groups. In 2022, I became the Czech U20 decathlon champion and qualified for the World U20 Championships in Cali, Colombia. I went there as the youngest athlete in the field, with the fifth-best score in the world that season. But nerves and expectations that were too high got to me: I didn’t clear a single height in the pole vault, and with that went any hope of a good finish. A tough lesson.
In 2023, I fought through an injury to make the European U20 Championships in Jerusalem. After eight events I was sixth, with a real shot at the top five, but the javelin let me down and I dropped out of the top ten. I finished with 7,499 points, a personal best. A big disappointment and a big motivation at the same time: I knew I had a lot of room to improve.
In the fall of 2023, I was invited to join the training group of Roman Šebrle, former world record holder and Olympic champion, someone I’d looked up to since I was a kid. In February 2024, I won my first senior medal at the Czech Championships, in the indoor heptathlon. The goal for the summer season was simple: break the elite 8,000-point mark.
Instead came a stress fracture in my foot. And that fall, two months after I moved to Prague to train with the group, came the eleventh event: on November 4, 2024, a week after my twentieth birthday, I was diagnosed with acute lymphoblastic leukemia.

The eleventh event
November 4, 2024.
Diagnosis.
A week after my twentieth birthday. Instead of a training camp in South Africa, I was looking at months in the hospital, chemo, and long days when you just don’t know anything.
I had just turned twenty. I kept feeling like I hadn’t really done anything with my life yet. Hadn’t lived, hadn’t achieved anything. So from day one I believed I had to beat this. I tried not to think about the worst.
I had an aggressive type of leukemia, so I needed a bone marrow transplant. Two donors turned up in the international registry. The guy who saved my life is from Poland. Someone I’ll never meet, but his blood runs through my veins. There are no words for that.
“I never let myself think I wouldn’t make it.”
I’ve got a song about it, too
August 30, 2026
First race
after leukemia
All year I’d been aiming for the European Transplant & Dialysis Sports Games in Arnhem, the Netherlands. I even got in my last training session on site. On the evening of June 25, 2026, the Games were canceled because of a heat wave.
So I made my own race at home.
An exhibition 100 m race at the Czech U22 Championships, at Stadion Míru in Tábor. I ran it with my closest friends from athletics, the people who pulled me through treatment and recovery.
Result
11.72
100 meters, 1st place. Czech U22 Championships.

What’s next
A short documentary.
I’m making it with my friend Jakub Homola. It’s not a film about medals and results. It’s more about what happens to you when life turns upside down overnight. About feelings, about fear, about how you start to appreciate ordinary things differently. It’s still in the works, and I’m not promising a release date or a final form yet.
We want to make an honest, sensitive look at my road back after leukemia. What does it mean for someone who spends hours moving every day to spend months in a hospital bed? What is it like to learn to walk, run, and train all over again? And how do you cope with all of it mentally? Those are the questions we want to answer.
Format
Short documentary (under 10 min)
Where to find me
I share my story on Instagram.

@petr__svoboda
I try to share my thoughts, feelings, and progress along the way. Going forward, I’d also like to raise awareness of what this insidious disease is really like, not only from the patient’s point of view, but also from the point of view of the people close to them. I want to show that behind the diagnosis there aren’t just numbers and medical terms, but real people with stories, emotions, and dreams. Whether you’re a patient, a family member, or just someone who wants to understand, I believe my Instagram can be a place for sharing and support.
