Your running data. Your AI. Your coach.
PB-Runner turns the AI you already use into a running coach: it knows your history, writes real sessions to your watch or phone, and helps you reshape your plan the moment life gets in the way.
Bring the AI you already pay for · Your data, downloadableBuilt for iPhone, Android, Apple Watch and Garmin
Set the goal. Make the plan to meet it.
Say what you're training for and your AI builds the programme, the whole way to race day or a week at a time. Then it's a conversation: how you're tracking, what got in the way, what to work on next. It rewrites what's ahead and keeps a coaching note about you, so each chat picks up where the last left off.
Describe any session.
Run it minutes later. Intervals, pyramids, progressions: any format, in plain language. It writes the session to your schedule and plays it through your run with live cues, on Apple Watch, on a Garmin, or on your phone. The watch runs it standalone, so the phone can stay at home.
Every write is proposed first. You confirm before anything lands.
Ask
Tell your AI what you want: a pyramid, a progression, 6 × 800 at 5K pace. Plain language, no builder screens.
Confirm
It drafts the week into your schedule and shows you exactly what it wants to write. Nothing lands until you say yes.
Run
The session builds itself on your phone and watch: target pace per rep, rep counts, recoveries.
Hear it
Haptic taps, beeps or a spoken voice walk you through every segment, and nudge you when you drift off target pace.
Analyse the result with your AI: every rep, every recovery; then use what you discover to calibrate the next one.
Training plans fail because they can't bend. Yours can.
On holiday and it's all trail? Say so.
Tell your coach in a chat: trail this week, a work thing eating Thursday, a race that moved. It reshapes the week around what you can actually do, and the new sessions are in the app and on your wrist before you've tied your shoes.
See the loop →Plans don't wake up with you. This coach does.
Resting heart rate, sleep, HRV and VO₂max, fused with your training load every morning. When the numbers say back off, your coach already knows.
See the recovery picture →Ask how you're tracking. The answer shapes next week.
What you ran, how it felt and how recovered you are shape the next week. Ask how you're tracking and your coach adjusts the plan, or the coaching note it keeps about you, the context it carries from one chat to the next.
See the progress picture →Your session, now on Garmin
PB-Runner now has its own Garmin watch app, free on the Connect IQ store. Today's session goes straight to the watch and it counts you through it step by step, with your target on screen, a buzz and a tone at every change, a three-two-one before a timed step runs out, and a nudge if you drift off the pace you were given.
When you finish, the run comes back into PB-Runner: the full GPS map, heart rate, pace, a time for every kilometre, and what you actually did in each rep, recorded against what was prescribed rather than as one undifferentiated run. It also saves on the watch as an ordinary Garmin activity, so your Garmin Connect feed carries on exactly as it did.
Already have years of runs in Garmin Connect? Bring them into PB-Runner with an easy CSV export, distance, time, pace and heart rate included.
The recovery side of the coaching, resting heart rate, sleep, HRV and VO₂max, is read from Apple Health and is not available from a Garmin today.
Share it your way.
A built-in editor for your finished runs. Put your stats over the map or your own photo, style it to match, then share it anywhere.
Keep the apps you love.
One tap shares a finished run to Strava, and your friends, kudos and segments stay exactly where they are. The share is write-only: PB-Runner never reads from your other apps, and never asks you to leave them.
“Can I record my kayaking session?”
No. Running is all we do.
We track the data others don't. Your Apple Watch already measures how you run, not just how far: we keep every sample, and your AI coaches off it.
