File Analysis
Turn activity files into readable workout context
Use the analyzer workflow when you want to inspect a workout export before comparing it, reprocessing it, or keeping it in your training archive.
Review route context when files include position data, and keep each imported workout tied to its original source file.
Inspect available streams such as pace or speed, heart rate, power, cadence, elevation, distance, duration, and other compatible metrics.
Keep source files available for original-file download, GPX export when route data exists, CSV exports, and future reprocessing.
Supported Workflows
Analyze files from services, devices, tests, and custom exports
The same private dashboard can hold provider imports and standalone files from unsupported tools or review workflows.
Upload common workout file formats from services, watch exports, lab files, firmware tests, review units, and one-off recordings.
Use stored original files for reimport and statistics regeneration workflows when you need a cleaner parse later.
After a file is imported, compare compatible recordings with provider workouts, benchmark reports, and device-to-device analysis.
FAQ
Workout File Analyzer FAQ
Can I analyze GPX and TCX files too?
Yes. Quantified Self supports GPX and TCX activity uploads alongside FIT, JSON, and SML files when the file can be parsed as a workout activity.
Is this a public FIT or GPX file viewer?
No. Quantified Self is a private training dashboard. Imported files are tied to your account so they can support analysis, exports, reprocessing, and comparisons without becoming a public upload.
Is workout file analysis free?
Manual uploads and core analysis are available on the free plan for up to 100 activities. Automatic provider sync and higher activity limits require a paid plan.
Next Step
Upload the file, inspect the workout, then decide what to compare
Start with one exported workout file, verify the available route and stream data, then keep it for later dashboards, exports, reprocessing, or benchmark comparisons.
