Garmin lactate threshold not updating?

Check your watch model and its test method first. Supported automatic detection can use wrist heart rate or a paired monitor. Guided tests use a compatible paired monitor. A chest strap is not a blanket requirement for every automatic estimate.

Check the method your device supports

Use your owner’s manual and Garmin’s current compatibility guidance. Do not follow instructions for a different model or assume every run must produce an update.

Work through these checks

1. Check that the relevant auto-detection setting is enabled.
2. Check that the watch has the VO2 max estimate and supported activity data required for its method.
3. Check the heart rate recording and any monitor pairing.
4. Allow for more qualifying activity history. An unchanged estimate may not produce a notification.

Do not chase a notification

Avoid turning ordinary sessions into repeated hard tests just to make a value move. Keep your goal, your plan and how you feel ahead of the screen.

Have a test result already?

Check the manual before entering it. On supported devices, manual entry can affect automatic detection settings. Keep a record of the value and date.
