"I have been coached by Mark for over 5 years now, and it's definitely been a worthwhile investment (especially compared to how much most triathletes spend on bikes and kit!!)Why Mark? Because of his scientific approach to everything, his eye for technical swim coaching, and his extensive knowledge of physiology. This allows him to work out each athlete's limiting factors and the most efficient way to improve them, given time constraints available around work and family."

"Mark is also good at looking beyond the numbers and understanding how personal circumstances, personality and preference affects how an individual engages with the programme. I enjoy and appreciate the fact that Mark gives as much attention and energy to me as a 40 something age grouper as he does his pro athletes.."
