My story

I found my way into triathlon in 2022 at the age of 28 and earned my pro licence after just one year in the sport. Unlike many athletes who transition to triathlon later in life, I didn’t grow up as a competitive athlete. My interest in sports science led me to study exercise physiology at university, where I discovered cycling. I entered my first race in 2018 at 24 years old. Since the beginning, I have been self-coached, constantly learning and developing both as an athlete and a coach.

In 2020, while racing for an elite cycling team in Switzerland and completing my master’s degree, a tragedy turned my life upside down. I lost my girlfriend to a brain tumour. Rebuilding my life after such a loss was an ongoing challenge, but sport became a source of focus and purpose, eventually leading me to triathlon.

My greatest strengths, resilience and perseverance, have already been tested in life’s toughest moments, and they continue to drive me toward new heights in my athletic career.

In 2025, after only three years in triathlon and in my second season as a professional, I won my first PRO race at Challenge Sir Bani Yas. One month later, I broke the 6-hour cycling world record.

In 2026, I qualified for the IRONMAN 70.3 World Championship and completed an IRONMAN in 7:51, marking another major step forward in my professional career.
