From zero to world records
I don't talk about training from theory. I talk about training I went through myself – from absolute zero to world records.
My journey started at age 30. I had never trained before – just after stubbing out my last cigarette, I started from scratch. Learning to swim, cycle, and run. Step by step. Day by day.
At the same time, I was working in a greenhouse. Training had to fit into real life – because that was the only life I had.
"It's proof that systematic work works – if you treat training as a process."
My real achievements
- 🏆 World Record in ultra triathlon – 5× Ironman
- 🌍 365 days of triathlon – the length of the equator (40,170 km)
- 🏃 Longest no-sleep run – 574 km in 86h14'
- 🥇 Multiple wins in ultra running and triathlon events
How I work with athletes
Why I do this
Because it's my passion. I'm good at it. I know how to design training that actually works.
Because guiding people toward their athletic dreams gives me purpose. This is work that matters.
And because doing it makes me grow too – as a coach, as an athlete, and as a person.
If you want your training to stop being chaos and start leading to real change – join me.
