How can I Import my Windows SportTracks database into TrailRunner

Problem: You switched to a Mac and want to import your SportTracks database into TrailRunner.
Solution: TrailRunner can import SportTracks Fitness Logbooks. Alternatively -- by using a third party plugin -- SportTracks can export its database as a Garmin TCX database. This also includes (almost any) additional data fields from SportTracks.
