Katinka Nyberg – Building a Global Trail Community with Vision, Heart, and Determination
Founder & CEO of Arduua | Certified Running Coach | Mountain & Skyrunning Enthusiast | Entrepreneur in Transformation
I’m Katinka Nyberg — founder of Arduua, mountain runner by heart, coach by purpose, and entrepreneur by nature.
My trail running journey began at 44, driven by curiosity and the desire for change. What started as a simple personal challenge has since grown into a global movement — a community of runners united by ambition, courage, and love for the mountains.
After 15 successful years as a tech entrepreneur — leading Atrox Development AB until its acquisition by Telia in 2018 — I chose a new path.
A path defined not by offices and deadlines, but by mountains, transformation, and the pursuit of human potential.
That path became Arduua.
My mission today is clear:
to make high-quality trail running training accessible to everyday runners — not just elites.
To help people believe in themselves, train smarter, and discover what’s possible when effort meets passion.
What I believe in
• Mountains belong to everyone — strong, slow, new, experienced
• Growth happens when things get steep
• Community makes us stronger than we are alone
• Consistency beats intensity — always
• The greatest transformations start with one brave step
