What is a TCX File Viewer?

A TCX (Training Center XML) file viewer is a tool that lets you open and visualize workout data stored in .tcx files. These files are commonly exported by Garmin and many fitness platforms and can include GPS tracks, heart rate, cadence, and more.

Why use a local viewer?

Many platforms require uploading your activity data to view it. This viewer runs entirely in your browser, keeping your location and health metrics private.

What data can I see?

You can view activity summaries, lap breakdowns, time-series charts (heart rate, speed, elevation, power), and GPS tracks when available.

Your Privacy is Protected

Your TCX files are processed entirely in your browser. No data is ever uploaded to our servers. Your workout data and GPS locations stay on your device.
