Troubleshooting & FAQ
Activity syncing#
My activities are not appearing#
If new activities are not syncing from your device, check the following:
- Check your connection — go to Account > Integrations and confirm your device provider (Garmin, Wahoo, Hammerhead, Zwift, or Rouvy) shows as connected.
- Upload your activity — make sure your activity has been uploaded to your device provider first (e.g. synced to Garmin Connect). Stride receives activities from these platforms, not directly from your head unit.
- Wait a moment — activities typically appear within a minute or two of being uploaded to your device provider. If importing bulk data, you will see a "Data importing" banner while processing is underway.
- Reconnect if needed — if your connection has lapsed, disconnect and reconnect the integration. This sometimes happens if you change your password on the device provider.
Strava activities are not syncing#
Strava is not a core integration. It does not sync your Strava activities to Stride. Instead, Strava is used to sync activity names and routes from Stride to Strava. To sync activities into Stride, connect a core integration such as Garmin, Wahoo, Hammerhead, Zwift, or Rouvy.
Importing history#
Garmin history is incomplete#
When you connect Garmin, Stride imports up to 5 years of activity history automatically. If you have older data, or the import did not work, there are two things to check:
- Historical data permission — when connecting Garmin, you must grant the "Export Historical Data" permission on the Garmin Connect authorisation screen. If you did not, you will see a warning on the Integrations page. To fix this, disconnect and reconnect your Garmin account, making sure to grant this permission.
- Data older than 5 years — to import your full history, use the bulk import tool at Account > Import. Request a full data export from Garmin at garmin.com (Account > Data Management > Export Your Data), then upload the zip file to Stride.
Zwift history is missing#
When you connect Zwift, Stride imports up to one year of your past activities automatically. To bring in rides older than a year, export them as .fit files from Zwift and upload them using the bulk import tool at Account > Import.
Import is stuck or failed#
If you see the "Data importing" banner for an extended period, the import may still be processing large files. Give it time. If the import fails, try the following:
- Make sure your file is a .fit, .fit.gz, or .zip archive containing .fit files.
- Try uploading a smaller batch of files if the archive is very large.
- Contact support if the issue persists.
Workouts#
Workouts are not syncing to my device#
If workouts are not appearing on your Garmin device, check the following:
- Workout import permission — your Garmin connection must have the workout import permission enabled. If it was not granted when you first connected, disconnect and reconnect your Garmin account, making sure to grant all permissions.
- Set your FTP — structured workouts use power targets based on a percentage of your FTP (Functional Threshold Power). If you have no FTP set, the workout cannot calculate the watt targets needed by your device. Go to Metrics and add your FTP manually, or enable automatic threshold estimation in Account > Profile.
- Sync your device — after scheduling a workout in Stride, sync your Garmin device with Garmin Connect (via the Garmin Connect app or USB) for the workout to appear.
Zwift workout sync#
Zwift supports automatic workout sync. When you schedule a workout in Stride, it will appear in your Zwift workout list the next time you open the game. You can also use the "Export to Zwift" button on any workout to download a .zwo file manually.
Performance data#
My power data looks wrong#
Stride flags activities with suspicious power or heart rate data automatically. If you see a warning on an activity, the recorded data may have been affected by a sensor issue (low battery, poor contact, interference). Check your power meter calibration and sensor placement for future rides.
My training zones seem off#
Training zones are calculated from your FTP and threshold heart rate. If your zones do not feel right, your threshold values may be out of date. You can:
- Update your FTP or threshold heart rate manually from the Metrics page.
- Enable automatic threshold estimation in Account > Profile, then use "Re-calculate Threshold History" to update from your recent activities.
Dates and timezones#
My activity times look wrong#
Stride uses your timezone setting to display all dates and times. If your activities appear at the wrong time of day, your timezone is likely incorrect.
To check or update your timezone, go to Account > Profile and look for the timezone picker. Stride auto-detects your timezone when you sign up based on your browser, but it will not update automatically if you travel or move.
Activities are showing on the wrong day#
If an activity recorded late at night or early in the morning appears on the wrong date, this is usually a timezone issue. For example, a ride recorded at 11pm in the UK would show as the next day if your timezone is set to a region ahead of yours. Update your timezone in Account > Profile to fix this.
Calendar and planner dates seem off#
The training planner, calendar view, and scheduled workouts all use your timezone to determine which day activities and plans fall on. If your weekly view does not match what you expect, check your timezone setting. This is especially common after travelling or if you signed up while in a different region.
