How does TrailRunner mini import and export the GPX file format

The GPX file 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

When you export routes in the GPX format to be displayed on other devices, the same applies. Some apps may not make a difference between track/route and way-points and may display all at the same time. To avoid this, you most likely want to export your route containing trackPoints only.

Background routes

When you select a route in TrailRunner mini, the course is displayed in the map. But sometimes you may want to permanently display the route in the map, e.g. for planning alternatives or by making them visible as your path to follow when using RaceBunny while you are on your way biking or hiking.

You either flag a route by selecting the flag in the right information area or by selecting the flag in the left list of routes:

How can I backup my files?

Problem: It's not really obvious to me where TrailRunner mini stores the main document containing routes. How can I backup these files?
Solution: TrailRunner mini stores files in the following locations:

The main container is here:

within that container, the following files are being stored:
Application Support/com.berbie.trailrunnermini/TrailNetworkStore.sqlite
Application Support/com.berbie.trailrunnermini/com.berbie.trailrunnermini.log

Hint: The __yourhome__/Library folder is invisible by default. But just hold down the option key while pulling down the Finder's "Go" menu to get there. Or you can make it permanently visible using the following terminal command:
chflags nohidden ~/Library/
or you can open it by typing the following into the Finder menu item Go > Go to Folder box:

How can I split a route or concatenate fragments?

TrailRunner mini offers options to work with route fragments:

Pasted Graphic

Select a route and also select a range in the elevation chart. Then choose the command to trim the route to the selection in the chart.

Select a route and also select a location in the elevation chart. Then choose the command to split the route at the selection into two route fragments.

Select a route and choose the command to reverse the course direction. In other words to make the end point the new start.

Select two route fragments and choose the command to join the two fragments into one concatenated route.

Adjust starting point
Select a route, preferably a round trip, and select a location in the chart. Then choose the command to set the starting point of the round trip to the select position making the old start point a simple transit location on the course of the resulting route.

Extended Route Notes

With TrailRunner mini 3.6 and above, you can add additional notes and attachments to routes. These are multiple images, text fragments and links to websites or any file on your hard drive.

To use this feature, select a route. In the right info area select the notes icon. Then either drag anything into this area or add a container by clicking the top right + icon.
Once you have added multiple containers you may reorder them by clicking and holding within the background area of a container until the container starts hovering and then dragging the container to reorder it.

This feature is free to all users that have bought a subscription and for users that have bought a lifetime license for TrailRunner mini 3.6 and above. Users that have bought a license prior the 3.6 release have to buy a subscription.
