GPSFunRunner 3D is a third party application which allows the comparison of two separate .tcx files within 3Dimensions
The initial interface menu allows you to view what two files will be imported into the GPSRunner 3D application for comparison in 3Dimensions.
The main program shows the training data in 3Dimensions with the height of the pillars on the route being representative of the speed at the recorded time.
The Demonstration version is provided with two .tcx files which can be imported using the Import button from the GPSRunner 3D menu. You can also import your own tcx files.
The Demonstration version allows you to import two of your own tcx files. The following image shows typically where you import the files from in Windows Explorer.
