Garmin changed their data access rules on August 1st, 2021. They now only allow access to 5 years of historic data. This is a rolling limit, so the 5 years goes back from whatever “today” is when you connect Garmin to CityStrides.
Any activities already synchronized into CityStrides will remain here, unless you delete them.
There may be workarounds along the lines of:
- Export your data from Garmin
- Import the data into a service that does not have this data access limitation
- Connect that service to your CityStrides account within your Settings page
- Pause that service after the old activities have arrived in CityStrides
If you are able to find a workaround for this issue, know that the syncing system will skip activities with the exact same start time. This will allow you to connect another service which may have some overlapping activities & not produce duplicates in CityStrides.
