RunSync help guide
Connect Garmin when you want RunSync to send structured running workouts to Garmin Connect so they can reach a compatible Garmin watch.
Create or sign in to your RunSync account, then make sure you can access the Garmin account you use with Garmin Connect and your watch.
RunSync does not ask for your Garmin password. You authorize access through Garmin's own connection flow.
Open the Garmin area in RunSync, choose the connect action, and follow the Garmin authorization prompts.
Grant the workout permission requested by RunSync. This allows supported structured workouts to be sent to Garmin Connect.
After Garmin returns you to RunSync, the Garmin page shows whether the connection is healthy or needs attention.
If the connection later expires or permissions change, reconnect Garmin before trying another workout sync.
