Training GPS-Sessions Tourbook On Linux

I use a free GPL software to get my training and hiking tracks from my old Aldi-/Crane-GPS-Clock via USB. This software is named crane_gps_watch and is provided via a repository on github.com. I could fetch the data via command line. This are text files with the file extension tcx.

I found another free software where I could import this files, get a visual presentation of my tracks and could add some more details to them, e.g. about weather conditions like wind velocity and direction, cloudy sky or rain. This software is named ‚MyTourbook‘ and you could get it from its homepage http://mytourbook.sourceforge.net/mytourbook/ .
