Who built this

Built by Collin Chartier. Boulder. Former pro.

USAT Olympic Trials qualifier. Raced professional ITU around the world. Twenty years in endurance sport.

I built this because most self-coached athletes deserve better than a generic Runner's World plan, but a real coach runs $975 to $2,977 a month. This is the same playbook I use, packaged for Claude.

The methodology

Pro-level training, not vibes.

Polarized training

80% easy, 20% hard. Most age-groupers train in the gray zone and stay flat. Your plan won't.

Block periodization

Focused blocks (base, build, peak, taper) instead of random hard days. You'll know why every workout is there.

PMC metrics (CTL/ATL/TSB)

Fitness, fatigue, and form tracked over time. Your coach sees the trends and adjusts before you break.

HRV-aware recovery

Bad sleep, high stress, sick? The plan flexes. You don't grind through a key session when your body says no.

What you get

A real coach, on demand.

1

A personalized training plan that adapts as your Strava data comes in.
2

On-demand session review. Open Claude, say "review my long run," and your Coach pulls the data and breaks down pacing, HR, effort, and recovery flags.
3

Plan adjustments when life or fitness changes. Overtraining, sickness, work travel, race date moves: the plan rebuilds around you.
4

Race-day pacing, fueling, and taper protocols built on my pro methodology. Marathon, ultra, 70.3.
5

My full coaching brain: periodization, PMC metrics (CTL/ATL/TSB), polarized training, HRV-aware recovery.

Before you buy, the honest stuff

This works inside Claude Desktop. To use it, you need Claude Pro ($20/mo, billed by Anthropic) and a Strava account (free tier works; a Strava subscription unlocks the Strava MCP connector for $12/mo). I don't charge for either of those. You own your Coach forever.

All sales final, no refunds. This is a digital download.
