What it does

Coaching that adapts to a real life.

Five things, in plain language.

Goal discovery

What's your Mile 50?

Not a generic intake form. A real conversation about why this goal matters, what's drawing you to it, and what shape your life's actually in. The plan starts from your answers — not a template.

Goal discovery
What time of year are you eyeing?
Late August.
Got it. Anything we should plan around — work travel, kids' summer schedules?
Two weeks of camp drop-off in July.
Then we'll keep July's volume modest and load August.
Adaptive plan

In pencil, not ink.

A rolling 1–2 week window. We rebuild around how the week actually went — your sleep, your energy, your life load.

FAQ

Honest answers.

Is this for beginners or experienced runners?expand_more
Both. We meet you where you are. If you're new to trail, we focus on durability before volume. If you're coming from road or another sport, we don't waste your base — we build on it.
How is this different from a Training Peaks plan?expand_more
A downloaded plan is set in stone. Mile 50 is a rolling 1–2 week window that rebuilds around how the week actually went — your sleep, your energy, your life. The plan is in pencil, not ink.
What does it cost?expand_more
Free during beta. After that, monthly or yearly — at a price that's significantly less than working with a human coach. Save the big spend for when you want face time with someone.
Do you train AI on my conversations?expand_more
No. Your conversations are used to build your plan and nothing else. Not to train AI. Not shared. Not stored beyond what your coaching needs.
Do I need a watch, Strava, or a heart-rate monitor?expand_more
No. Logging a workout takes 10 seconds and the plan adapts whether or not you wore a watch. If you connect Strava or your watch, that signal helps too — but it's not required.

Let's go.
