Exporting data to gpx file to load into another route plotting application, I find the plot goes "off the scale". The cause has been tracked to others to one or more rogue trackpoint entries in the export which have both lat & long = 0. As this on the equator south of Greenwich it is rather a long way from the route of my run in England !
Circumvention is to manually delete the rogue entries from the gpx file, but this is tedious & time-consuming when there are lots of them.
Garmin please fix this.
