The Marathon Clinic exists because runners deserve better than a generic plan and a wish of luck. The marathon is a specialist event: 42.195 km has its own physiology, its own pacing, its own way of going wrong, and it deserves a specialist's eye.

We borrowed the word “clinic” on purpose. A good clinic examines before it prescribes, treats people as individuals and states what it cannot know. The free generator checks the inputs you provide and follows a transparent method. Paid coaching adds the practitioner who reads your training and responds to it.
Your generated plan is yours to keep. Inside coaching, we move a missed run and carry on rather than resetting the relationship. A human answers your messages, usually the same day, and AI remains a quiet working layer rather than the coach.
We keep our roster small and our focus on the marathon. We’d rather coach a hundred runners brilliantly than a hundred thousand averagely. The brand is new; the craft behind it is not. It draws on more than a decade as an elite endurance athlete, and the coaching that grew out of it, brought together in Sydney in 2026 and offered now to runners worldwide.
“After a decade in high-performance sport, much of it as the athlete, Jason kept seeing the same thing: good runners handed generic plans, training hard, and breaking. Diagnose first, then prescribe. Understand the runner before the plan.”
The tools combine published evidence, transparent calculations and the Clinic’s coaching method. The same inputs return the same result, and where a model is uncertain or only an estimate, we show that rather than inventing precision. Nothing you get here is improvised by a language model.
That took deliberate work: taking what a good coach actually knows and building it into something you can use yourself, rather than handing your training to a generic AI and hoping. We do use AI to help us work, to research, draft and build faster, but never to write your plan. The method was shaped by human coaching judgement, the sources are open to inspection, and the limits matter as much as the maths.
Most of what we make is free and meant to stand on its own: the tools, a full marathon plan from the generator, and the guides. None of it is a trial or a tease, and none of it is locked behind a wall.
When you want a real coach in it with you, reading every run and reshaping the week around your life, that is what coaching is for. The free work gets you a long way; coaching is for when you want someone in your corner the whole way.
Everything here is shaped for the one event, so your plan is a specialist’s.
The generator validates what you enter; a coach reads the fuller story when you work with us.
We cut the plan back to the sessions that actually move your time.
You leave understanding your own running, whether you reach for a free tool or train with us for a season.
How those convictions become the training is its own story: the one idea, and the ten pillars behind every plan we write.
