Pacer — AI Running Coach

Pacer — AI Running Coach이란?

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.
