What is a TCX file?

A TCX file is Garmin Training Center XML. It stores workout and activity data such as tracks, laps, distance, time, heart rate, cadence, and calories.

TCX is a readable XML activity format used by older Garmin workflows and training platforms.

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.
