CoachFrom the Coach guide
Keep your tracking setup.
Runs in Apple Health start your plan. Route and heart-rate data add more guidance.
What Coach needs
Runs recorded to Apple Health, by your watch or phone app. Your tracking setup must save the relevant data to Health.
A GPS route for each run
Coach uses your pace to find the warm-up, the hard part, and the cool-down. Route data also helps read your threshold test.
Heart rate during runs
Coach checks the effort of each run and sets your heart-rate zones from the available readings.
Heart rate and sleep at night
Coach reads these to help show recovery and fatigue. A watch worn at night or a ring can supply them. They must reach Apple Health.
Check your own data
After you connect Health, open Settings → What Coach can see. It shows what Coach found in your last 30 days and what it does when data is missing.
