Heldoorn Coaching

Heldoorn Coaching provides personalised endurance training for runners and triathletes, from beginners to experienced athletes. Led by Frank Heldoorn, a coach with world-level triathlon experience, the brand helps clients pursue their individual sporting goals through tailored training plans, periodic testing and practical advice. Coaching can address running or triathlon preparation, with guidance on areas including nutrition and technique. The approach considers both the training needed to progress and the importance of an effective, balanced process, helping athletes build towards their ambitions step by step.

Heldoorn Coaching also offers swim analysis, clinics and training stages. Swim analysis includes clear explanations and practical technique tips, with video footage used to help athletes see what they can improve. Client feedback describes the advice as directly useful in the water. Training plans can be adjusted through regular discussion, helping athletes fit preparation around work and personal commitments. Whether the aim is to start running, improve performance or prepare for a long-distance triathlon, Heldoorn Coaching combines individual planning with ongoing support to help athletes develop and work towards their next goal.
