Miles: Your Running Coach

Miles is an AI running coach connected directly to your running data.

Connect Garmin, Coros, or Apple Health and your runs sync seamlessly as you train. From there, Miles does what a good coach does: it reads every run, tells you what it means, and adjusts the plan with you.

Talk to it like a chatbot — but one that already knows your last six months of running. Ask about race strategy, a missed week, or a sore knee, and get an answer grounded in your own training.

AN ANALYSIS AFTER EVERY RUN Splits, heart-rate zones, pacing, decoupling — deep analysis, plainly written. Every workout read on its own terms, whether it was intervals, a tempo, a long run, or an easy day.

A SCHEDULE THAT ADJUSTS BY ASKING Tell the coach about a missed run or a busy week and it edits the schedule with you. Completed runs and planned workouts sit side by side, so the week ahead is always in view.

CRITICAL SPEED, THE PACE YOU CAN HOLD FOR AN HOUR Predicted continuously from your runs and race history. The basis for your lactate-threshold pace and heart-rate zones. The same model elite coaches use — without the lab visit.

RACE TIMES THAT MOVE WITH YOUR FITNESS Best-in-class predictions from your own fitness curve, recomputed each week. Mile through marathon, with confidence bands.

Tuned for runners who need no extra motivation. If you know what threshold pace means and you want a coach that does too, this was built for you.
