Triathlon coaching, South West UK and online

Triathlon Coaching

Triathlon coaching built for your race, from your first sprint to Ironman. Written by me, delivered through TrainingPeaks, from the South West of the UK and coaching worldwide.

Triathlon coaching for every distance

I'm Tom Cooling, and I coach triathletes from a first sprint all the way to Ironman, long course and the extreme XTRI races like Norseman. Whether you're chasing your first 70.3 finish or a podium at Ironman Wales, coaching with Horsepower puts you and your dream at the centre of it, built around your target race, your life and your numbers, located in the South West of the UK and coaching online worldwide.

Every plan is written by me and delivered straight into TrainingPeaks, built in three-week blocks so the load lands and the hard sessions are dosed the way the research says fitness is actually built. Swim, bike, run and the transitions in between, all prepared properly. Quality over quantity, every time.

What triathlon coaching with me actually covers

Triathlon is really four sports, not three, because the transitions and the way the three disciplines feed into each other decide as much as any single one. So we work the whole picture: a swim that leaves you fresh for the bike, bike pacing that protects your run, and a run built on the durability to hold form when you are tired. Around that sits the strength work, the fuelling you rehearse until it is boring, and the heat and race-craft preparation the bigger days demand.

It suits the athlete who wants a coach reading their actual sessions, not a template downloaded and forgotten. First-timers who want to reach the start line genuinely ready, age-groupers chasing a championship slot, and plenty of people in between. Wherever you are in the UK or further afield, the coaching is delivered online from the South West, so the only thing that changes is your postcode, never the standard.
