COACHING

Triathlon, IRONMAN & Marathon Coaching

From your first triathlon to a full IRONMAN, we coach every distance – sprint, Olympic, 70.3 and full – alongside standalone marathon and running coaching (we've covered every Marathon Major over the years) and one-off goals like Channel swims and ultra running. Can't commit to a full-time coach? Our consultancy service reviews your training, plans your race, or advises on nutrition and kit.

A Triathlon Coach for Every Level

We've coached athletes running their very first event through to those qualifying for World Championships. There's no gold/silver/bronze tiering here – every plan is built around you, your life, and your goals, not a template.

Why Choose an OE Triathlon Coach?

Optimal Endurance is a team of 8 coaches – current and ex-professional long course athletes – each limiting how many athletes they take on, so plans stay bespoke rather than copy-paste. You get sessions and feedback through Training Peaks, regular calls, unlimited text/email contact, and a community of 180+ athletes for support along the way, including UK and Mallorca training camps.
