A GPX file (GPS Exchange Format) is an open, XML-based file format designed for storing and sharing geographic data. It is widely used across fitness apps, GPS devices, and mapping tools to represent routes, tracks, and waypoints.
Because GPX is an open standard, it is one of the most universally supported formats for GPS-based activities.
What data does a GPX file contain?
GPX files can include:
- GPS tracks and routes
- Latitude and longitude points
- Elevation data
- Timestamps
- Waypoints and markers
- Basic activity metadata
GPX focuses on location data rather than advanced fitness metrics.
When should you use a GPX file?
GPX files are best when you:
- Share routes or GPS tracks across platforms
- Use mapping or navigation tools
- Need maximum compatibility between devices and apps
- Visualize workouts or outdoor activities on maps
Limitations of GPX files
While widely supported, GPX files have some limitations:
- Limited support for heart rate, power, and cadence
- Larger file sizes than binary formats like FIT
- No support for structured workouts or training plans
If you need richer performance data, another format may be more suitable.
