Data Types

We provide the data file in .FIT, .GPX or .TCX format (depending on device) that was uploaded to Garmin Connect from supported devices.


Flexible and Interoperable Data Transfer Protocol β€” called β€œFIT” for short β€” is an interoperable binary data transfer protocol designed to be compact and extensible. This is the most current data file created by our devices. It's developer-friendly and provides extensive data metrics, including the capability of creating your own. Visit the FIT SDK site to learn more about this file type and obtain the free SDK.
