How to upload automatically via the Garmin Connect mobile app:
If your Garmin device is Bluetooth-enabled, you can download the Garmin Connect mobile app, create a Garmin Connect account, and link to your Strava account by going to Settings > 3rd Party Apps > Strava. Once activities are wirelessly uploaded to the app via Bluetooth, they will appear on Strava a few moments later. After your first upload, Garmin will also sync your past 90 days of activity to Strava.
How to upload automatically using Garmin Express:
To upload using your computer, download and install Garmin Express and follow instructions to add your device. On the Strava website, visit strava.com/upload/device and find the Garmin option to authorize a link to Strava. If you don't already have a Garmin Connect™ account, you'll be prompted to create one. Once you've established this connection, any new activities uploaded to Garmin Connect™ will automatically sync to Strava. After your first upload, Garmin will also sync your past 90 days of activity to Strava.
How to stop automatic syncing with Garmin Connect:
Should you need to disconnect Garmin and Strava for any reason, you can do this on your Settings page at strava.com/settings/profile. Note that you may also have to disconnect your accounts from the Garmin Connect side as well which can be found at http://connect.garmin.com/account.
How to manually upload an activity file to Strava:
Upload activities directly to Strava from your hard-drive mountable Garmin devices. Note that this option is not available for devices that use the ANT+ agent. Visit strava.com/upload/select and click Choose file. Browse to the Activities folder on your connected device and select the files that you'd like to add.
- If you recently connected your Garmin account to Strava, wait until your first new activity is synced successfully. This can be performed with a short test activity that is later deleted. After your first successful sync, Garmin will also sync your past 90 days of activity to Strava.
- We experience occasional delays when syncing from Garmin's side, especially during peak upload times. You can check whether Garmin Sync is working by checking out their status page and referring to the "Strava" status (6th from the bottom). The Strava status page also displays uploads from Garmin Connect. To avoid the wait, you can use the file upload option directly from your device or export the .TCX file from Garmin connect and upload manually.
- To refresh the connection between Garmin Connect and Strava, disconnect Garmin Sync from your Strava settings, then reconnect. To disconnect, visit Settings in the mobile app or website, and select "disconnect". To reconnect, follow the authorization flow after selecting connect. Remember, Garmin sync is not triggered until the first new activity is uploaded to Garmin after your accounts are reconnected.
How to sync Garmin activities to Strava as private by default:
Any privacy settings on your Garmin Connect account are unfortunately not transferred when the activity is synced. We're working with Garmin on ways to improve this experience. In your Strava Privacy Settings, you can enable an option to make your activities private by default. Any activity can be made public after it has been uploaded.
