Since yesterday afternoon, I’ve been experiencing a persistent issue with my Garmin Enduro 3.
After a long swimming session, my Recovery Time was correctly set at 63 hours. However, after recording a walking activity, the recovery time suddenly dropped to 0 hours and hasn’t updated since.
At the same time, my Training Readiness has been stuck at 63, which is exactly the same as my nightly HRV value, as if no other metrics (sleep, stress, acute load, etc.) are being considered in the calculation.
I have already tried the following:
• Manual restart of the watch
• Verified heart rate and sleep tracking settings
• Reset Training Readiness via Garmin Connect
• Forced device synchronization
• Deleted the walking activity
But nothing has changed.
I also want to highlight that this issue is present both on the watch and in Garmin Connect, and it started right after installing the 13.35 software update.
These things shouldn’t happen — these watches let you down like this, making them completely unreliable.
