Mark's ethos

Mark has been encouraging everyone to take up open water swimming and has been helping all ages and all abilities achieve their ambitions. He gets to know his clients individually and works closely with them so they enjoy the journey and have the best performance possible.

As an advanced performance coach, Mark has helped individuals of all ages achieve their goals. By being fulltime coach Mark gives you the attention you deserve.

Individual training plans are based on:

  • Your past sporting background

  • Current level of fitness

  • Aspirations and the demands of your event

  • Injury prevention

  • Strength and conditioning

  • Technique development

  • How to swim faster in a wetsuit

  • When life gets in the way, I provide alternative workouts and advice with ongoing reviews and analysis of your training data so you have the best competition possible. Some clients have been working with me for 6 years and are still improving or venturing into different or more challenging events.
