24-hour swim for Cancer Fighters

Every workout I do, every start and every kilometer I cover this year has one goal - to give strength to those who are fighting for their health not by choice, but by necessity. I'm entering more ultra-challenges to help children struggling with cancer.

Meet challenge

From the ring to the ultradistance - my way to help

I'm a boxing and kickboxing coach, and for the past few years I've also been passionate about triathlon. I entered the world of ultra in 2025, winning 3rd place at the Obiliad in my hometown, competing in the Harda Bitch Ultratriathlon and completing 2× Ironman.

New year, new challenges, same goal: to help

This year I'm setting myself more challenges: 24-hour swim, participating in Harda Bitch again, and competing in 3× Ironman in September. This is also the first time I'm organizing a charity fundraiser, and it's an important step for me, because every sports challenge is not only a test of one's limits, but also a way to make a real difference.

Every kilometer is support for children struggling for health

I combine my passion for sports with charity work, believing that through my efforts I can give strength to those who face cancer every day. I want to inspire others, show that activity can bring good and every kilometer swum is a gesture of support for children fighting for health.
