Where 200 KB matters

A 204,800-byte file: twice the default body limit of most API frameworks, and a common cap for photo and signature uploads on application forms. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Express body parsers	100 KB by default	Rejected with 413 unless the limit is raised.
Amazon DynamoDB items	400 KB per item	200 KB fits, even after base64 encoding takes it to about 273 KB.
Azure Service Bus, Standard tier	256 KB per message	Fits as raw bytes, but not once base64-encoded.

Testing notes for GPX

Devices add heart rate, cadence and temperature in extension elements from other namespaces. A parser must skip what it does not recognise.
GPX writes latitude before longitude, the opposite of GeoJSON and KML. Converters that copy the numbers across without swapping them put tracks in the wrong place.

Verify your copy

This file is created in your browser, so it has no direct URL for curl or wget. The generator is designed to produce reproducible bytes. After saving, compare the checksum with the SHA-256 value above.

sha256sum sample-gpx-200kb.gpx     # Linux
shasum -a 256 sample-gpx-200kb.gpx # macOS

On Windows, run Get-FileHash sample-gpx-200kb.gpx -Algorithm SHA256 in PowerShell. For scripts and pipelines, save the file once and keep your own copy.
