Where 1 KB matters

The smallest practical test file: 1,024 bytes, small enough to travel in a single network packet. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Ethernet	1,500 bytes (typical MTU)	A 1 KB payload fits in one packet with its headers.
Browser cookies	4,096 bytes per cookie	1 KB is well inside the limit; the 5 KB sample is over it.

All 1 KB sample files

Use this file for

Smoke tests in CI that must run in milliseconds
Testing activity upload in fitness and mapping apps
Checking distance, speed and elevation calculations

Testing notes for GPX

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.
The time element is optional. A file without it has no speed or duration, and code that assumes timestamps fails on routes drawn by hand.
