At the TRTHLN Academy, we believe triathlon coaching isn't about control – it's about clarity. As a Dutch Level 3 (NTB) Certified Triathlon Trainer, my mission is to provide athletes with a "clearer compass" rather than just a harder training plan.

My coaching philosophy is built on sustainability and Athlete Autonomy. I specialize in helping ambitious recreational (age-group) athletes integrate performance-level training into a life filled with professional and family responsibilities. I don't believe in the "more is better" mantra. Instead, I focus on data-driven insights – utilizing tools like TrainingPeaks and WKO5 – to ensure every session serves a specific purpose for your recovery and long-term development.

Whether you are preparing for your first sprint or aiming for a personal best at the Ironman distance, my approach remains the same: we build a structural foundation that respects your physical limits and daily reality. I am here to help you understand the "why" behind your training, helping you navigate fatigue, missed sessions, and the pressure of race day.

With the TRTHLN Academy, you aren't just following a schedule; you are learning to master the sport. My goal is to prevent overtraining and keep the joy in the process. Let’s build a training path that fits your life, ensures your health, and delivers the performance you’ve worked for.
