Run Planner

Adaptive training for Garmin runners

One good run, every other day.

Run Planner reads your recent runs and heart rate from Garmin Connect, works out where your fitness actually is, and puts the next session on your watch. Hard enough to count. Easy enough to recover from.

In private development, not yet open to the public

How it works

No sixteen-week plan. Just the right next run.

  1. Connect Garmin

    Sign in and link your Garmin Connect account. Run Planner reads your runs (heart rate, pace, distance, elevation) and your daily resting heart rate. Nothing else.

  2. It learns how you run

    From that history it estimates your heart-rate zones, threshold pace, current fitness and fatigue, and how your heart rate responds to pace on a given day. It refits after every run.

  3. Your next session lands on your watch

    Before each run day it picks a session (easy, steady, tempo, intervals, hills or long), sizes it to you, and sends it to your Garmin Connect calendar. Your watch syncs it like any other workout.

The rules it plays by

Challenging, at your level, and it tells you why.

  • Never two hard days in a row.Quality sessions are always separated by easy running.
  • Easy means easy.Easy runs are capped by heart rate, not pace, so they actually recover you.
  • Gradual, not heroic.Weekly load grows about 5%, with a hard ceiling on sudden spikes.
  • One longer run a week.It never stretches more than 15% beyond your recent longest.
  • Sore? Say so.Report joint pain after a run and the next session gets easier and flatter.
  • Every session explains itself.You'll see why it chose today's run, in plain English.

Your Garmin data

Used for one thing: planning your running.

What we read

Running activities: heart rate, pace, distance, cadence and elevation over time.

Daily resting heart rate.

What we send

Structured workouts to your Garmin Connect calendar, so they sync to your watch.

What we never do

Sell or share your data, show you ads, or use it to train AI models.

GPS route coordinates aren't used, and they're discarded when activities are processed.

Leaving

Disconnect Garmin or delete your account at any time, and your data is deleted. How to delete your data · Full privacy policy
