How does TrailRunner mini import and export the GPX file format

The GPX file format (https://en.wikipedia.org/wiki/GPS_Exchange_Format) is an open standard that describes geographic information.
Within that format there is a conceptual difference between three types of point information:

  • Track-Points: this is a raw recording representing a course. TrailRunner mini creates track-points as a result of a calculated route (the course you see on the map)
  • Route-Points: : this represents a stop point on a route and is represented as a transit location (routing pin) in TrailRunner mini. Given two transit locations, TrailRunner mini calculates a track between these using the OpenStreetMap Network.
  • Way-Points: this represents a landmark in TrailRunner mini.

Whenever you export files from external sources and import them in TrailRunner mini, try to keep the data straight within the expectations of TrailRunner mini. Some applications may export tracks as a series of wpt-tags which leads to serious misunderstandings within TrailRunner mini.

There are some type conversion tools out there that may help. Like http://www.gpsbabel.org
