# Why don't Zwift activities forward from Garmin to Terra?

**This is expected:** Garmin deliberately does not forward third-party uploaded activities (for example, from Zwift) through the API Terra uses.

* If a user sees those activities on Strava or Training Peaks, those platforms received the data from a different source.
* **The exception is manual uploads.** Garmin makes data available when an activity is manually uploaded as a FIT file, or when the activity is edited to appear to originate from a Garmin device. That's how a workout originating elsewhere can reach Terra.

Note that this is still not Garmin forwarding third-party data, it's Garmin exposing data that now looks Garmin-originated.
