Many cyclists and runners love using Zwift for interactive training. It’s fun, motivating, and helps you connect with others. But things can get frustrating when you encounter the issue of Zwift Not Syncing To Garmin within your Garmin Connect account. You finish a great ride or run, but it doesn’t show up on Garmin. This problem is common, and it can disrupt your training records, stats, and even your motivation.
Let’s dive deep into why Zwift may not sync with Garmin, how to fix it step by step, and what you should know to keep your fitness data accurate and complete. Even if you’re new to Zwift or Garmin, this guide will help you understand, troubleshoot, and solve the syncing issue.
Why Syncing Zwift With Garmin Matters
Syncing is more than just moving data. For many athletes, Garmin Connect is the main place where all workouts, health stats, and achievements are stored. If Zwift rides or runs don’t transfer, you lose:
- A full training history
- Accurate performance trends
- Health insights (like VO2 max or Training Load)
- Social sharing and challenges
- Personal motivation
Missing data can also affect third-party apps that connect to Garmin, like Strava or MyFitnessPal. For serious athletes, even small gaps in data matter.

How Zwift-Garmin Syncing Works
Before troubleshooting, it’s useful to know how the sync process happens:
- You complete a workout or race in Zwift.
- Zwift uploads your activity to its server.
- If you linked your Garmin Connect account in Zwift, Zwift sends the activity to Garmin.
- Garmin Connect receives the data and adds it to your timeline.
This process depends on both Zwift and Garmin servers, your account settings, and sometimes your device or internet connection.
Example
Imagine you finish a 30km Zwift ride. You see it in Zwift, but when you check the Garmin Connect app or website, it’s not there. Something along the sync chain failed. Let’s explore why.

Common Reasons Zwift Does Not Sync To Garmin
Several factors can break the sync. Here are the most common, with clear explanations.
1. Account Link Not Active
Sometimes, your Garmin Connect and Zwift accounts are not linked, or the link has expired. Even if you set it up before, reauthorization is sometimes needed after software updates or password changes.
2. Internet Connection Problems
If Zwift cannot upload your activity due to a weak or unstable connection, syncing fails.
3. Zwift Server Issues
Zwift’s servers sometimes experience delays or outages. This can cause uploads to be slow or stuck.
4. Garmin Connect Outages
Garmin’s servers are not always perfect. Maintenance or outages can delay incoming activities.
5. Activity Type Not Supported
Some Zwift activities (like custom workouts or events) may not sync correctly if Garmin doesn’t recognize the format.
6. Duplicate Activity Detection
Garmin Connect may ignore activities if it thinks they are duplicates. For example, if you record the same ride on a Garmin device and Zwift at the same time.
7. Corrupted Fit File
Zwift saves activities in a .fit file. If this file is corrupted, Garmin cannot read it.
8. Privacy Settings
If your Zwift activity is set to private or hidden, it may not sync to Garmin.
9. Time Zone Or Date Errors
If your computer or device has the wrong time or date, it can confuse the sync process.
10. Software Bugs Or Updates
Sometimes a new update introduces bugs that break syncing until fixed.
How To Check If Zwift Is Syncing To Garmin
Not sure if your activities are syncing? Here’s how to check:
- Log in to Garmin Connect (website or app).
- Go to your recent activities.
- Look for the Zwift workout by date, time, and type.
- If you see the activity, syncing works.
- If not, try searching by keyword (e.g., “Zwift”).
If your activity is missing, it’s time to troubleshoot.
Step-by-step Troubleshooting: Fix Zwift Not Syncing To Garmin
Let’s go through the solutions, from easiest to more advanced.
1. Confirm Accounts Are Linked
- In the Zwift Companion App or at my.zwift.com, log in.
- Go to Settings > Connections.
- Check if Garmin is connected.
- If not, click Connect and log into your Garmin account when prompted.
- If already connected, try disconnecting, then reconnecting.
This refreshes the link. Many users fix their problem here.
2. Check Internet Connection
A weak Wi-Fi signal or dropped connection can cause failed uploads.
- Try uploading another activity.
- Restart your router or switch networks.
- On mobile, switch between Wi-Fi and mobile data.
Zwift needs a stable connection to send data to Garmin.
3. Wait For Server Delays
Sometimes, the problem is not on your side.
- Check the Zwift Status Page (status.zwift.com) for outages.
- Check the Garmin Connect Status at Garmin Connect Status.
- If servers are down, wait and try later.
Activities usually upload automatically once the service is restored.
4. Manually Upload Fit Files To Garmin
If auto-sync fails, you can upload your ride or run manually.
How To Find Your Fit File In Zwift
- On computer: Go to Documents/Zwift/Activities. Find the file with today’s date and time.
- On iOS/Android/AppleTV: Use the Zwift Companion App to email the FIT file to yourself, or contact Zwift support for help.
Upload To Garmin Connect
- Go to Garmin Connect (website).
- Click + > Import Data.
- Select the FIT file and upload.
This gets your activity into Garmin, but won’t fix auto-sync for the future.
5. Check Activity Type And Privacy Settings
- In Zwift, open the activity and check its type (Ride, Run, Workout, etc.).
- Make sure it’s not set to Private.
- Set to Public or Followers so Garmin can receive it.
Some activity types or private settings block syncing.
6. Avoid Duplicate Records
If you record the same ride on a Garmin device (like an Edge, Forerunner, or Fenix) and in Zwift, Garmin may ignore the second upload. Try:
- Only recording in Zwift, or
- Deleting one of the duplicates in Garmin Connect.
7. Update Software
Keep both Zwift and Garmin Connect apps updated. Check for app updates in the App Store/Play Store and restart your device after updating.
8. Check Date And Time Settings
On your computer or device, open Date & Time settings. Ensure it is set to Automatic or correct manually. Wrong dates can cause file errors and prevent upload.
9. Reauthorize Zwift-Garmin Connection
Sometimes, the connection token expires. Disconnect Garmin from Zwift, log out of both, then log back in and reconnect to refresh permissions.
10. Contact Support
If nothing works, contact Zwift and Garmin support with your account email and details of the failed activity.
