Who John Coaches
PEC athletes range from complete beginners taking their first steps in triathlon to elite-level competitors chasing podiums and qualification slots. What they share is a commitment to improving — and John meets every one of them where they are.
Sessions span all three disciplines — swim, bike and run — with coached group sessions, one-to-one appointments, indoor Zwift sessions and bike fitting all available. Based in Glasgow, PEC serves athletes across the central belt and beyond, with online coaching available for those further afield.
The PEC Philosophy
Endurance sport is hard. It demands structured work, honest feedback and a coach who understands your life outside of training. At PEC, you'll never be handed a generic plan and left to get on with it.
