Pacer - AI coach that re-plans your week from how you actually ran

by•
Pacer reads your COROS data (official API, read-only), estimates your fitness, and builds a marathon plan on Daniels / Hansons / 80-20. Then it does the part static plans can't: re-planning every week from what you actually did — bad sleep, elevated resting HR, a skipped tempo, a sore achilles. All math is deterministic code; the AI never guesses your paces. Hard safety rails stop overtraining. Free while early. Garmin/Strava waitlist open.

finally linked my coros and it auto-built a pretty solid 16-week plan around my actual paces, then nudged my long run down after a rough sleep score yesterday. love that the AI never picks my splits

 Thanks Mackenzie — really glad the Coros link worked smoothly and that the 16-week plan actually fits your paces (not just textbook numbers). The sleep-aware long-run nudge is exactly the kind of adjustment we want it to make on its own: pull back when recovery is rough, don't push through fatigue.

And yeah, the "never picks your splits" thing is intentional — your watch data is the source of truth, the AI just plans around it. Curious how the next few weeks feel as you start running against the plan. If anything feels off (too aggressive, too easy, missing pieces), just holler.
