The Marathon Clinic
How it works

From one run to the finish line.

The Clinic is a connected flow: we read, we prescribe, we put it on your watch, and we keep reading. Every step fits the same runner — yours.

A practitioner watching

Coach Casey reads every run from day one and gives you a plain-language read. Add a human coach the moment you want one in your corner.

AI, then human
·The method, at a glance

Specialist training, made humane.

Paced off real running

Your paces are read from a run you actually did, not a finish-time you hope for. Honest in, honest out.

Injury-aware progression

We cap weekly load growth and bake in down-weeks, because the fastest plan is the one you finish healthy.

A taper done right

The last three weeks are choreography, not panic. You arrive rested and sharp, not flat or fried.

Read first. Run smarter.

Build your plan in under a minute and see what a real read feels like.
