A complete marathon coaching system that lives inside your AI assistant. Phase-based training for first-time marathoners 12–24 months out, guardrails that keep you honest, and a genuine check-in every Sunday.
Not a training PDF. A coach that knows your name, your race date, and when you're going too hard.
Finish Strong (first marathons), Performance (chasing a time), High Volume (experienced racers). Fourteen onboarding questions route you deterministically — paces calibrated from your recent fitness, never your goal. Graduate between tracks as your durability proves out.
Base, build, peak, taper, race week, and post-race recovery — scaled to your race date, with down weeks, tune-up races, and fueling programmed in.
Hard rules against ramping too soon or training through pain. The coach's first job is getting you to the start line healthy.
Every Sunday, a genuine read on your actual week — never a template. Adjustments included.
Big moments get noticed: first 10-miler, longest run ever, taper week. The coach marks them with you.
Race, goal time, recent results, mileage, course, fueling, sleep, injuries, vibe. Fourteen answers and the whole system — track, paces, phases — configures itself.
Your marathon becomes a tracked goal in your assistant, with phases that tick over as training progresses.
Choose a vibe at install. Switch any time — just ask. The personality is seasoning; the coaching is the meal.
Honest, direct, data over feelings — but never cold. Calls out excuses kindly and doesn't let them stand.
"That wasn't an easy run. Your heart rate says otherwise. Let's talk about it."
Notices effort out loud and celebrates small wins specifically. Still honest about the data — never flattery.
"Remember your first 3-miler? Today you ran 14. That's not nothing. That's everything."
Theatrical, high-energy, relentless about consistency. The intensity lives in the personality — never in your training plan.
"BEAUTIFUL. Sixteen miles before breakfast. Your legs are writing checks your race day will cash."
No apps to download. No accounts to create. It installs into the assistant you already use.

It's built for first-time marathoners roughly 12–24 months out from race day. Closer than that? It still works — the phases just compress. Further out? It'll build your base patiently.
Yes — that's exactly who it's for. The onboarding meets you where you are, and the guardrails exist precisely so beginners don't do what beginners always do: too much, too soon.
Tell your coach. The pain rules are strict — it will never tell you to train through pain — and the plan rescales around time off instead of trying to "make up" for it.
Any time. Just say the word. Some runners start with the Drill Sergeant and switch to the Encourager during peak weeks. No judgment.
No. If you have one, the coach can use the data. If not, perceived effort and honesty work fine.
