About TCX
TCX is an XML activity format used by older Garmin devices and the Training Center desktop application. It carries trackpoints, heart-rate data, and cadence; many fitness apps export it as an alternative to GPX or FIT.
How to view a TCX file
- Open the viewer.
- Drag your TCX file (.tcx) onto the page, or click the + in the Places panel.
- The file renders on a 3D MapLibre globe. Use the right-hand panel to toggle background layers (borders, labels, roads, buildings, transportation, places, terrain).
- Click features for details, or use the bottom toolbar to convert to another format.
