The GPS positioning system have made a large difference for tracking training activities.

Hans' radio-orienteering friend Rolf Svensson started it; tracking the path during a radio-orienteering competition. And, since Hans got a GPS unit for his 50th birthday in 2007 he started to use it also.
A great way to inspect the tracks is by uploading them to GPS Visualizer.
Another alternative is comparetracks.com. See the radio-orienteering night race of Hans, Jan and Rolf, August 2008 in Eskilstuna:
Hans first GPS; Garmin eTrex Venture® Cx, had the capability of saving the track data as GPX files directly.
The second GPS; Garmin Forerunner ® 405, did not stored the tracks in GPX format but the TCX format, which is basically a GPX file with added information like heart rate and distance.
This calendar shows the GPS-tracks that Hans created in May 2017.
With the track files and map data it is possible to create animations of the path.
Here are some animations of GPX track files.

2014-02-21: Kortvasan 30 km, Mora

GPX and TCX are both XML file formats. Both contain GPS waypoints, tracks, routes, etc.
GPX is an open format, free for development use without licenses.
TCX is a proprietary format developed by Garmin. It allows additional information such as heart beat and cadence.
