What is the difference between track and route in a GPX file

Question

I wanted to know what is the basic difference between a GPX track and route file

Answer 1

A route is a sequence of waypoints, its the plan for your navigation. A track is the recorded path you did actually follow while trying to implement the plan (the route).

As GPX files a different XML schema is used for routes and tracks. Here are examples: http://cycleseven.org/gps-waypoints-routes-and-tracks-the-difference

Answer 2

Originally, a GPX route was supposed to consists of only waypoints important to navigate along them from origin to destination, still allowing differences in the actual track taken due to, for instance, traffic conditions or construction sites. Hence, the GPX track was supposed to consists of a much more dense sequence of actually recorded locations on the way from waypoint to waypoint. A pretty good scheme can be found on Wikipedia.

Since Stefan's link is broken, you will find the latest official GPX definition and documentation at topografix.com.

However, GPX tracks are sometimes used for all purposes: planning tours, navigating (particularly when cycling or hiking) or recording the actual track.
