As founder and head coach of Ferrum Endurance, I believe every athlete deserves a personalized approach, though fitness fundamentals remain universal. Endurance success relies on resilience, aerobic capacity, and—most importantly—enjoyment in training, which drives motivation and accessibility.

Balancing training with personal and work life is essential. I help athletes realistically plan weekly training based on their goals, adapting classic periodization to individual needs.

We use leading tools such as TrainingPeaks, BestBikeFit, WKO5, and INSCYD for detailed performance analysis. Monitoring heart rate, power, sleep, and nutrition is key to tailored coaching. Honest, open feedback shapes the training process, built on trust and confidentiality.

Founded in 2018 after earning my Ironman Certified Coach license, Ferrum Endurance now supports 60+ athletes from beginners to world champions. My aviation background helps accommodate irregular schedules. Our expert team includes Gaby (Ironman coach & psychologist), Peggie (TTN3 coach & physiotherapist), Marije (physiotherapist & manual therapist), and Marijn (ultrarunning coach). Together, we deliver science-based coaching, injury prevention, mental support, and a strong community.

Each athlete is assigned a lead coach, while analysis and mental guidance remain closely integrated, ensuring optimal, personalized support to reach your goals.
