Professional middle- and long-distance triathlete. Driven by the joy of sport, curiosity about what comes next and the will to keep learning.

My journey

Step by step.
Always myself.

It all started in the water. I was a competitive swimmer as a child. But I wanted to run and try something new, too. At the end of August 2012, I went to my first triathlon training session.

The sport has stayed with me ever since. My path gradually led from short-course racing to longer distances. I wasn’t right at the front in my U23 years. But I kept going, kept learning and got better over the years. After several Swiss U20 and U23 championship titles, I also won the elite Swiss sprint triathlon title in 2023 and raced at the highest level of short-course triathlon, the World Triathlon Championship Series (WTCS).

Alongside professional sport, I work 50% as a business analyst. After my master’s in Health Sciences and Technology at ETH Zurich, I still value that different perspective. When there’s time: cooking, documentaries and podcasts.
