To fix a situation where you find runna not syncing with garmin, you must disconnect and then reconnect your Runna account within the Garmin Connect app settings. This issue usually happens because the authentication token between the two platforms has expired or failed to refresh after a recent software update. By removing the link and establishing a fresh connection, you force the systems to handshake again and resume the data transfer process. If the sync still fails after this, check your internet connection and ensure your Garmin watch has successfully synced with your phone first.
Reasons Runna isn’t syncing with Garmin

The primary cause for sync failures is a broken handshake between the Runna server and the Garmin Connect API. When you link these services, Garmin issues a secure digital “key” that allows Runna to push workouts to your watch. If this key becomes invalid—often because of a password change, an app update, or a long period of inactivity—the data transfer halts immediately.
Another common reason is a mismatch in account permissions. Garmin requires specific read-and-write permissions to receive third-party workouts. If you accidentally revoked these permissions in your Garmin account settings, Runna can’t send your training plan to your device. This often occurs if you have multiple Garmin accounts and are logged into the wrong one on your phone.
Finally, connectivity bottlenecks play a role. Your Garmin watch must first sync its internal data to the Garmin Connect app via Bluetooth before it can pull new workouts from external sources. If your watch has a pending firmware update or is struggling with a low-battery state, it may pause all background data syncing to preserve power. This varies by model — check the label on your specific device to see if it supports third-party workout integration, as some older legacy models lack the necessary software architecture to receive structured workouts directly from external apps.
Disconnect and reconnect the integration
This fix is for users who have confirmed that their accounts were previously linked but have stopped passing data. You need to fully reset the connection to clear out any corrupted background data.
First, open the Garmin Connect app on your smartphone and navigate to the settings menu. Find the “Connected Apps” or “Third-Party Apps” section. Locate Runna in the list of authorized services and select the option to disconnect or revoke access. Once you have done this, open the Runna app on your phone. Go to your profile or settings tab, find the “Connect to Garmin” option, and tap it to initiate a new login sequence.
You’ll be redirected to the official Garmin sign-in page. Enter your credentials carefully. If you use a social login like Google or Apple to sign into Garmin, ensure you use that same method here. After the authorization screen appears, confirm that you grant Runna permission to “Write” workout data to your account. This is the most critical step; if you don’t check the “Write” box, the sync will appear successful but no workouts will actually show up on your watch. If you’re uncertain about your current permission levels, you can review them at the Garmin Connect account management page. Once the apps are re-linked, wait about two minutes, then force-sync your Garmin watch by pulling down on the home screen of the Garmin Connect app.
Update the workout manually
If the automatic sync remains stuck, you can force the transfer of a specific workout. This is a great way to verify if the problem is a total system failure or just a temporary delay.
Open your Runna app and navigate to the current day’s workout. Look for a button or icon labeled “Sync to Garmin” or “Push to Garmin.” If you don’t see this, ensure your app is updated to the latest version via the App Store or Google Play. When you tap this button, the app sends a direct signal to the Garmin servers to queue your specific workout.
This method is useful if you have a race coming up and can’t wait for the background sync to catch up. However, this is a manual workaround; if you have to do this every single day, it indicates that your background sync permissions are still likely misconfigured. A common mistake people make is trying to sync while the watch is currently recording an activity. If your watch is in “Activity Mode,” it will block incoming data transfers to prevent system crashes. Always ensure your watch is idle on the main watch face before attempting a manual sync. If the manual push fails, try restarting both your phone and your watch, then attempt the push again while both devices are connected to a stable Wi-Fi or cellular network.
Check your watch compatibility
For those with older devices, the issue might be hardware-based. This fix helps you determine if your watch is actually capable of receiving the workout structure that Runna provides.
You should verify that your specific watch model supports “Garmin Workout” files. Not every device handles structured training plans, such as interval sessions or heart-rate-based targets. If you’re using a basic fitness tracker, it might not have the software to read the complex data packets that Runna sends.
It’s worth the time to check your watch’s specifications on the manufacturer’s website if you have owned it for more than three years. If your model is listed as “incompatible” with structured workout downloads, you won’t be able to sync the plan directly. In this case, the effort of trying to force a sync is wasted. You’re better off manually creating the workout in the Garmin Connect app using the data from your Runna plan. This requires more effort, but it’s the only way to get the workout on your screen if the device hardware is the bottleneck. This isn’t for everyone; if you value convenience over data tracking, you might simply prefer to follow your plan by looking at your phone screen while you run rather than trying to force a sync that the device can’t process.
What not to do
- Don’t uninstall the Garmin Connect app unless you have already removed the watch from your Bluetooth settings, as this often leaves “ghost” connections that prevent future pairing.
- Avoid repeatedly toggling the “Sync” button in the Runna app every few seconds, as this can trigger a rate-limit block on the Garmin API, preventing any data from moving for up to one hour.
- Don’t factory reset your watch to fix a sync issue, as this is almost never the cause and will cost you all your stored personal records and custom watch faces.
- Refrain from using third-party “bridge” apps to move data between Garmin and Runna, as these often conflict with the official integration and can cause duplicate workout entries.
How to stop it happening again
Consistency is the best way to keep your accounts talking to each other. If you follow these habits, you’ll rarely face a sync failure.
| If you’re doing this | Do this instead | Why |
|---|---|---|
| Closing apps completely | Keep Garmin Connect running in the background | It needs to stay active to receive pushed files |
| Syncing on low battery | Charge your watch above 20% | Most watches disable sync to save power |
| Changing passwords often | Update the link immediately | Old tokens become invalid as a security measure |
| Ignoring app updates | Enable auto-update for both apps | New firmware often fixes communication bugs |
Frequently asked questions
Can I sync Runna workouts to my Garmin watch if I have a free account?
Yes, you can sync workouts regardless of your subscription tier. This feature is a basic function of the integration between the two platforms. If you encounter issues, ensure your account is fully verified and that you have granted the necessary read-and-write permissions.
Why does my Garmin watch show a different workout than Runna?
This happens when your watch hasn’t received the latest update from your training plan. Your watch stores a local copy of your workouts, so you must perform a manual sync in the Garmin Connect app after modifying your schedule.
Is it safe to use my Garmin credentials in the Runna app?
Yes, it’s safe because you use the official Garmin authentication portal. Runna never sees your password, receiving only a secure token to verify your identity. You can revoke this access at any time through your Garmin account security settings.
How long does it take for a workout to appear on my watch?
Syncing typically takes less than sixty seconds. Once you have a solid connection, the workout should appear in your Garmin Connect “Training Calendar” almost immediately. If it fails to appear after five minutes, check your phone’s internet connection and background data settings.
What happens if I have two Garmin watches on one account?
The Runna app pushes workouts to the device set as your “Primary Wearable” in Garmin Connect. If you use multiple watches, you may need to manually select the active device in your settings. Note that multi-device sync capabilities vary depending on your specific watch model.
