The limit is just me

The last project was my toughest challenge for a long time.

Completing the most challenging adventures and ultra-endurance challenges

After setting cycling world records on all major continental crossings, I completed the first triathlon around the world — circumnavigating the globe by swimming, cycling, and running over 25,000 km. After that, it was time to find out what was possible by taking on my toughest endurance challenge yet. In the summer of 2024, I completed 120 Ironman-distance triathlons in 120 days, setting a new world record for the most consecutive triathlons.

When I am not on a big adventure or training for one, I share the mindset and lessons from my challenges with companies and organizations across Europe. I have written several bestselling books, and films about my adventures have been featured on TV, Netflix, and in cinemas.

456 kilometres of swimming
21.600 kilometres of cycling
