Who you'll be working with
A coach who has done it, not just prescribed it.
Mike has been a personal trainer for over 15 years. Ironman Wales in 2012 started his move from rugby into endurance sport; since then, four full Ironmans, five halves, and Ironman All World Athlete Bronze in 2023, 2024 and 2025.
He coaches beginners through to experienced age-group athletes — in person at his studio near Crickhowell and Brecon, and online anywhere. Every plan is built around your goal, your fitness and the time you realistically have.
