What is a GPX file?

A GPX file stores GPS tracks, routes, waypoints, latitude, longitude, elevation, and timestamps in an XML format that mapping apps can read.

GPX is useful when you want a map-friendly track that can be opened by route planners, mapping tools, and many sharing workflows.

What is a FIT file?

A FIT file is a compact activity file format used by Garmin and many sports devices. It can include GPS, heart rate, power, cadence, laps, and device data.

FIT is common for Garmin, Wahoo, COROS, and other endurance devices because it stores compact activity data with GPS and sensor streams.
