Many people who love running, cycling, or simply tracking their fitness rely on two powerful tools: Garmin devices and the Strava app. Garmin watches are trusted for recording accurate activity data, while Strava is famous for social sharing, analyzing workouts, and finding motivation from friends. But sometimes, the connection between these two breaks. You finish a workout, expect it to appear in Strava, but nothing shows up. Frustrating, right? If you’ve landed here, you’re likely searching for answers—and you’re not alone. This guide will help you understand why Garmin activities might not sync to Strava and, more importantly, how to fix the problem.
How Garmin Connect And Strava Work Together
Before diving into troubleshooting, it’s important to know how Garmin Connect and Strava share data. When you record an activity (like a run or ride) with your Garmin device, it first uploads the data to the Garmin Connect app or website. From there, Garmin Connect automatically sends the activity to Strava if you have linked your accounts. This process usually happens within a few seconds to a few minutes.
However, several things can go wrong along the way. Understanding the flow helps you spot where things might be stuck.
Here’s a simple overview:
| Step | Action | Potential Issue |
|---|---|---|
| 1 | Record activity on Garmin device | Device not saving or uploading |
| 2 | Sync activity to Garmin Connect app/website | No internet, app crash, sync error |
| 3 | Garmin Connect uploads activity to Strava | Accounts not linked, permission issue |
| 4 | Strava displays your activity | Strava server error, duplicate data |
Knowing this, you can see there are several steps where syncing might fail.
Common Reasons Garmin Activities Don’t Sync To Strava
When your Garmin activity won’t sync to Strava, the cause is usually one of a few main issues. Let’s break them down:
1. Device Not Synced To Garmin Connect
Your Garmin watch or bike computer must first upload the activity to Garmin Connect. If this does not happen, Strava cannot get your data.
2. Accounts Not Connected
If your Garmin Connect and Strava accounts are not linked, syncing is impossible.
3. Internet Or Server Issues
A slow or unstable internet connection, or an outage on Garmin or Strava’s servers, can block syncing.
4. Permissions Problem
Sometimes, you may have denied Garmin permission to share data with Strava.
5. Outdated App Or Firmware
Old versions of Garmin Connect, Strava, or the device’s firmware can cause glitches.
6. Activity Type Not Supported
Some special activity types (like Yoga or Golf) may not transfer to Strava.
7. Corrupted Activity File
Rarely, the activity file can be damaged during recording or uploading.
Some of these are obvious, but others are easy to overlook. For example, many people forget to check if their apps are updated, or if a recent update broke the link between accounts.

Step-by-step Troubleshooting Guide
Let’s walk through each step you should take to solve Garmin-to-Strava syncing issues. Start with the basics and move toward advanced solutions if needed.
1. Check Garmin Connect Sync
First, confirm that your activity has uploaded from your device to Garmin Connect.
- Open the Garmin Connect app on your phone.
- Look for your recent activity. If you don’t see it, your device hasn’t synced.
- Try syncing manually: Open the app, tap your device icon, and select Sync Now.
If the activity does not appear, check:
- Is your phone’s Bluetooth on?
- Is the Garmin device charged and nearby?
- Are you logged in to Garmin Connect?
If you still can’t see your activity in Garmin Connect, the problem is between your device and the app—not with Strava.
2. Confirm Garmin Connect To Strava Link
Next, make sure your Garmin Connect account is actually connected to Strava.
- Go to the Garmin Connect app.
- Tap the menu (three lines), then Settings, then Connected Apps.
- Tap Strava and confirm the connection is active.
If it’s not connected, follow the prompts to link your accounts. You’ll need your Strava username and password.
Pro tip: Sometimes, accounts can become unlinked after a Strava or Garmin update. Disconnect and reconnect if you suspect something is wrong.
3. Review Permissions
Even if your accounts are linked, Garmin needs permission to send activities to Strava.
- In the Connected Apps section, tap Strava.
- Ensure you’ve allowed sharing of all activity data—not just some types.
If you see a permissions error, disconnect Strava and reconnect, making sure to allow all permissions when prompted.
4. Update Apps And Firmware
Outdated software is a hidden cause of many syncing issues. Make sure you have the latest versions:
- Update the Garmin Connect app (via App Store or Google Play).
- Update the Strava app.
- Check for updates to your Garmin device firmware (this is usually found in the device settings or via Garmin Express on your computer).
If you’ve updated recently and problems started, a bug may be present. Sometimes, rolling back or waiting for a fix is needed.
5. Check Internet Connections
Syncing requires reliable internet on both your phone and your Garmin device (if Wi-Fi enabled).
- Make sure your phone is connected to Wi-Fi or mobile data.
- Try syncing on a different network.
- Check for known outages on the Garmin or Strava status pages.
6. Wait And Retry
Occasionally, Garmin or Strava servers are busy. Syncing can be delayed by a few minutes or even an hour.
If your activity eventually appears, there’s no need to panic. If not, continue troubleshooting.
7. Manually Export And Upload Activities
If automatic syncing fails, you can still transfer your activity to Strava manually.
From The Garmin Connect Website:
- Log in at connect.garmin.com.
- Find your activity and click on it.
- Click the gear icon, then Export Original.
- Save the .fit or .tcx file to your computer.
- Go to the Strava website and upload the file using the Upload Activity option.
| Method | Steps | When to Use |
|---|---|---|
| Automatic Sync | Device → Garmin Connect → Strava | Normal use, accounts linked |
| Manual Upload | Download file from Garmin → Upload to Strava | Syncing fails, urgent upload |
Manual upload is a reliable backup, but it won’t solve the underlying syncing problem.
8. Clear App Cache Or Reinstall
Sometimes, a corrupted app cache can block syncing.
- On your phone, go to settings, find the Garmin Connect app, and select Clear Cache.
- Do the same for the Strava app.
- If problems persist, uninstall and reinstall both apps.
After reinstalling, re-link your accounts.
9. Check For Duplicate Activities
Strava sometimes blocks duplicate uploads. If your activity appears in Strava but not as expected (e. g. , missing data, split into two activities), check for duplicates. Delete one and try syncing again.
10. Contact Support
If you’ve tried everything, reach out to Garmin or Strava support. Provide them with:
- Device model and firmware version
- Phone model and OS version
- Screenshots of the problem
- Steps you’ve already tried
They may be aware of current syncing bugs or outages.
Advanced Troubleshooting For Persistent Problems
If syncing issues keep happening, there could be deeper causes. Here are some advanced tips:
Check Activity File Integrity
Corrupted files can prevent syncing. If you export a. fit or. tcx file and Strava rejects it, the file may be damaged.
How to check:
Upload the file to a file repair tool like fitfiletools. com. If errors are found, try repairing and uploading again.
Test With A Different Account
Try connecting a different Strava or Garmin account. If syncing works, the issue might be with your profile, settings, or a data limit.
Factory Reset Your Device (last Resort)
If all else fails, reset your Garmin device to factory settings. This clears all data and often solves deep software bugs, but you’ll lose unsynced activities.
Important: Back up your data before resetting. Only do this if you’re comfortable with the risks.

Differences Between Garmin And Strava Data
Some users notice that data in Strava looks a bit different from what they see in Garmin Connect. For example, calories, elevation gain, or moving time might not match exactly.
Here’s a look at why:
| Metric | Garmin Connect | Strava | Reason for Difference |
|---|---|---|---|
| Calories | Based on device HR, personal data | Strava’s own formula | Different algorithms |
| Elevation Gain | Uses device barometer | Corrected by Strava maps | Strava smooths data for accuracy |
| Moving Time | Device auto-pause settings | Strava recalculates | Different pause detection |
This is normal and not a sync problem. Strava processes data in its own way for consistency across all devices.
Non-obvious Insights And Tips
Many guides miss some small but important details that can make a big difference. Here are two insights beginners often overlook:
1. Activities older than 90 days usually won’t sync automatically.
If you connect Garmin to Strava for the first time, only activities from the past 90 days (sometimes less) will transfer. For older workouts, use manual upload.
2. Privacy settings can block syncing.
If your Garmin activity is marked as private or hidden, it may not upload to Strava, or it may show up as private there too. Check your privacy settings in both apps.
How To Prevent Syncing Problems In The Future
It’s better to prevent syncing issues than to fix them every time. Here’s how:
1. Update Apps Regularly.
Set your phone to auto-update Garmin Connect and Strava.
2. Check Connections After Major Updates.
After a big phone, app, or device update, verify that your accounts are still linked.
3. Keep Your Device Storage Clear.
If your Garmin device is nearly full, it may struggle to save or upload activities.
4. Log Out And Back In Every Few Months.
This can refresh app connections and prevent authentication errors.
5. Monitor Official Status Pages.
If you notice a widespread outage, it’s probably not your fault. Be patient and try later.
6. Avoid Using Multiple Accounts.
Using more than one Garmin or Strava account on the same device can confuse syncing.
When To Use Third-party Sync Tools
Some athletes use third-party apps or services to sync Garmin data to Strava or other fitness platforms. Examples include Tapiriik or RunGap. These can help if you use several devices or apps, but they add complexity and sometimes cost money.
Caution: Always review privacy and security settings before giving third-party apps access to your data.
Syncing For Teams, Clubs, And Challenges
If you train with a group or join challenges, missed activities can be frustrating. Strava clubs and leaderboards rely on up-to-date data. Encourage your group to check their sync settings regularly. For big events, remind everyone to double-check their connections before race day.
Real-world Example
Let’s say you just finished a 10K run with your Garmin Forerunner. You open Garmin Connect and see your activity, but it’s missing in Strava.
- First, check if your accounts are linked.
- If yes, try uploading a new test activity (even just a short walk) to see if it transfers.
- If only the old activity is missing, export and upload it manually.
- If new activities won’t sync either, disconnect and reconnect Strava in Garmin Connect.
- Still no luck? Update all apps and try again.
Most issues can be fixed in a few minutes with these steps.
When It’s Not A Sync Problem
Sometimes, you expect an activity to sync but it doesn’t—and it turns out the problem is not with syncing at all. Maybe the workout wasn’t saved on your device, or the GPS didn’t record properly. Before blaming syncing, check that the workout appears correctly in Garmin Connect.
If it’s missing there, focus on your device settings first.
