ESCI Level 1About
I'm Thomas Lykke Sørensen, a certified endurance coach based in Denmark, specializing in triathlon, cycling, and running. With 15 years of experience in endurance sport 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 racing: I've completed 15 IRONMAN-distance races, including the IRONMAN World Championship in Kona 2022 and Nice 2023. Through my company, Coach Lykke Endurance, I coach athletes in Denmark and abroad with personalized online training plans, continuous feedback, and smart use of TriDot, lactate testing, and advanced performance analytics.
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 sport for 15 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 strengthens my scientific, data-driven approach to coaching.
