PACR
The running coach app that actually coaches.
Most running apps are excellent at telling you what you just did. Very few will tell you what to do tomorrow, and fewer still will say anything useful while you are out there. PACR writes the session, adjusts it for the state you are in, and calls it out loud as you run.

Four things a coach does that an app usually doesn't.
Tracking is solved. These are the parts most running apps leave to you, at exactly the moment you are least able to do them well.
A coach tells you what today's session is, and why. PACR rebuilds it at 4am from your last run, your real threshold pace and the weather, so you open the app to a decision rather than a blank screen.
The hard part of coaching is the easy day. When yesterday's session cost you, today gets capped — and the voice keeps capping it while you argue with it in your head at kilometre two.
Feedback after the run cannot save the run. Blocks are called two beats before they change, pace nudges arrive when you drift past your own tolerance band, and the rest is deliberate silence.
Say “cut it short today” out loud and the session reshapes around it. A plan you cannot renegotiate is a plan you eventually just stop opening.
Plan, tracker, or coach.
Three ways runners currently solve the same problem, and what each one actually does for you.
What the coach actually reads.
No questionnaire, no self-reported feelings, no goal-setting wizard. Three inputs, every morning.
Your last run
Split drift, cadence, and how hard the end felt. It is the difference between a plan that assumes you did Sunday's long run and one that knows you did.
Your real pace
Threshold modelled from your own sessions rather than a calculator, so targets move in seconds week to week instead of jumping between tiers.
Today's climate
Heat, humidity and wind on the exposed stretch, converted into an honest pace for the session you are about to run.
What it sounds like.
Coaching, not commentary. Long silences are a feature — you are running, not listening to a podcast about running.
Running coach app questions.
What people want to know before they let an app tell them what to run.
What does a running coach app do that a tracking app doesn't?
A tracking app records the run you chose. A coach decides the run for you, based on the state you are actually in, and then coaches it while it happens. PACR does the deciding at 4am and the coaching in your ear.
Is an AI running coach as good as a human coach?
It is not the same thing. A human coach knows your life, your history and what you are like when you are lying about being fine. What software does better is turning up every single morning, reading yesterday's data properly, and never being too busy to rewrite today.
Do I need a running watch to use it?
Bring your watch and your headphones if you have them. The coaching happens through your ears while you run, so headphones matter more than any particular piece of wrist hardware.
Does the app work for any distance?
Yes — the same daily rewrite runs behind a 5K block and a marathon block. Only the shape of the weeks and the sessions inside them change.
Is PACR free?
There is a free plan while you build the habit. The app is on Android; you can start from the Play Store or straight from this site.
Will it stop me overtraining?
It will argue with you about it. When your last runs say you are carrying fatigue, the plan caps the day and the voice keeps it capped — the coaching decision most runners are worst at making for themselves.

Pick the distance and the coach builds the block around it.
