In any discussion of routes, navigation or GPS devices, you have probably seen people mentioning ‘GPX files’. GPX is shorthand for GPS eXchange Format and is a type of file that’s really helpful to anyone who loves the outdoors, and is the most popular way of saving and exchanging routes.
What’s in a GPX file?
You can actually open a GPX file in any text editor, and you’ll get something like the image here. While this looks complex, all most people need to know is that it is a list of precise locations, in order, that make a up a route for walking, running, cycling or any other activity. This route can then be placed on top of a map for printing or following on screen.
