TrailRunner

TrailRunner gets more open and is now a team-player with a partner application called LoadMyTracks from cluetrust. This means you are now able to download your tracks from any GPS device, especially the Garmin ForeRunner series. And this is how it works:
First off, you need a calibrated map. Then, connect your GPS unit to your Mac by using one of the recommended methods. Visits the cluetrust website to get more information on that.
Then, go to File > Import > Data from GPS unit.
Now LoadMyTracks will fire up and will download all tracks from your GPS unit. When done, TrailRunner comes up again, asking you what tracks you'd like to import.
The Import can be done in two ways. Import course as one piece or Import and merge tracks. Import course as one piece just imports the track as it is. The good thing about this option is: it doesn't alter or harm your existing tracks. The bad thing about this is that the new track lays on top of any of your existing tracks in the map and has like no connections to the rest. But if you want to extend your net of tracks, and add new crossings and track courses, then you need to use the Import and merge tracks option. TrailRunner then tries to find as much similarities of the new track to your existing ones and will only add courses that are new to your map. Due to the very complex nature of the merging algorithm and sometimes poorly collected data by the GPS unit, this might not always give you results that 100% satisfies you.
At times, you will get tracks that have a course parallel to an existing track but TrailRunner did not recognize that they ought to be the same. When this happens, select the track you would call the master-track — the track you want to keep — and then select File > Consolidate > Merge onto selected track. All tracks that are parallel to the selected one are then reduced onto the master-track.
Please note that all these operations are very complex and therefore I can't give you undo (yet). So you better keep a save backup.

TrailRunner NanoMaps have been redesigned a bit to match more the visual appearance of Apple iPod designs.

From the original post: After struggling very long on how to describe a route in a very compact and portable way without using expensive GPS-Units which – if running trough the woods – wouldn't really do it anyway, I now added this kind of export. So if you are the lucky owner of the all so cool iPod Nano, this feature really is the best way to stay on track. With NanoMaps every waypoint on your route is displayed with a snap-shot of the map-area around it. Additionally the map is rotated in a way that the direction you are coming from is always at the lower edge of the screen. The orange arrow then shows you the direction you should turn to. The biggest benefit now is, that even if you did not put every possible track into your map you can still see that there are other tracks at a crossing. Because it is not possible to have subfolders in the nano Photo-Library, green squares with a readable route-code in the overview mode help you to find the route you are looking for.
So buy a nano, download some Podcasts, export your NanoMap and have fun with your exercise…
