In upcoming version 4.1 of my Run 5k app, I’m adding support for exporting data out of the app. I strongly believe that data liberation should exist in all applications and services despite the fact it can require significant amount of time to do properly. In 4.1, you will be able to export complete GPX file for each run you did with Run 5k.
What is GPX
GPX is de-facto standard for exchanging GPS tracks, waypoints, and similar GPS related data between applications and services. It stands for GPS Exchange Format and was created by Topografix. Current version of the specification is 1.1.
Over time, companies like Garmin have added Extensions to the original specification – thus you can include things like heart rate to it. Which all later lead them to create an expanded format called TCX which allows you to transfer many fitness-related bits of information.
