ESCI Level 1About
I’m an endurance coach based in Aarhus, Denmark, specializing in triathlon, cycling, and running. With over 15 years of experience in endurance sports and a data-driven approach, I help athletes perform at their best — from beginners to highly competitive age groupers. I combine scientific training principles with real-world experience from more than 10 IRONMAN races, including multiple World Championship qualifications in Kona and Nice. I coach athletes through personalized plans, continuous feedback, and smart use of TriDot and advanced performance testing.
Philosophy
Training should fit life — not the other way around. I believe in building sustainable progress through consistency, data, and honest communication. Every athlete is unique, so I tailor training to each individual’s lifestyle, motivation, and physiology. My goal is not just to make athletes faster, but to help them enjoy the process, understand their data, and build confidence through structure and science-based methods.

Experience
I have been involved in endurance sports for more than 14 years and have coached athletes since 2023. I work with athletes of all levels — from beginners preparing for their first sprint triathlon to competitive age groupers aiming for podium finishes. My coaching integrates physiological testing, structured periodization, and detailed data analysis. Before coaching full-time, I built a career in digital analytics and performance optimization — a background that now strengthens my scientific and analytical approach to coaching.
