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.

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.
