RunnerOS predicts your finish time from your own results, adapts every week to how your body actually feels, and explains every workout in words — not data overload.
No spam. One email when we launch. That's it.
10:15–10:45/mi — comfortable pace. Today builds your engine, don't chase speed.
Green light for today's run.
🏁 108 days to race day
"Your easy runs are drifting fast. Slowing them down is what gets you to sub-2."
Not a pace calculator with a chatbot glued on — a system that reads your training and answers the only question that matters: what should I do today?
Record or upload a 30-second run clip today, straight from your phone. AI form scoring lands next — it spots your single biggest injury risk and gives you one clear cue to fix it. Like having a coach watching every stride.
Report pain and your week softens automatically. High fatigue eases the load. A race inside two weeks builds its own taper. Your plan reads your body, not a textbook.
Your finish time is calculated from your own PRs and monthly fitness checks — the same math elite race-predictor tables use — not a generic estimate for "runners like you."
Easy, tempo, interval, and long-run paces derived from your actual times. Log a new fitness check and every pace updates with you.
Create a run, let your crew vote on time and place, see who's in, track who actually shows up, and hand out kudos — no group-chat poll chaos.
Every workout explains what to run, why it matters, and what your body is telling you — in clear words, not charts you have to decode.
Pain reports outrank the training plan — always. RunnerOS backs off before a niggle becomes six weeks on the couch.
One number — 0 to 100 — built from consistency, workout quality, recovery, and sleep. How ready you are, at a glance.
Two minutes: your level, your training days, your race. Add a PR if you have one — your first prediction appears instantly.
One clear workout per day, with the pace and the why. After each run, 30 seconds of feedback — effort, pain, fatigue, sleep.
Every week rebuilds around your feedback. Monthly fitness checks tighten your prediction. The plan gets smarter as you get fitter.
Early access opens soon. One email when it does — that's the whole deal.
