It happens to me if the gpx has been converted from a track to a route. Presumably because the track creates a trackpoint every few minutes & all are converted to waypoints.

It depends on the format of the downloaded file. If you save off the file as a 'GPX track' using one of the converter websites such as Bikehike or GPS Visualizer (or Garmin BaseCamp) - see previous thread entry below - it should display as a line minus the waymarks.

Open the file in a text editor:

delete: xmlns="http://www.topografix.com/GPX/1/1”
insert: xmlns="http://www.topografix.com/GPX/1/0”

Save the change

and the file can be imported into Basecamp.

I've seen problems with GPX files saved from Basecamp, not loading into MemoryMap. GPSBabel from https://www.gpsbabel.org/ fixed it.

GPSVisualiser has a GPS/GPX conversion page:
http://www.gpsvisualizer.com/convert_input
and might do it.

BikeHike displays and outputs GPS files in various formats including GPX. Relevant part of Help page is 'Uploading & Downloading to a GPS Unit':

Hello Elton,
It might be worth checking which version of Tracklogs you are using and consider upgrading to the latest version– it’s available free from their website.

I’ve downloaded the .gpx file from your website and encountered the same problem when I try to import it into Garmin Basecamp.
However, when I create my own .gpx file using Tracklogs, there are no issues getting it into Basecamp.
Looking at your .gpx file info, it looks like you might be using an earlier version of Tracklogs (v3.12.05 ?). I am using the latest version of Tracklogs (V3.18.02).

The probllem was caused by the <extensions> section. Removing this (long) section in a text editor allowed it to load it in Basecamp. An easier way is to load it into a website such as http://www.gpxeditor.co.uk/ and save it again. The track ideally also needs a name to show up in devices on on the desktop, which can be added at that point.

We are making gpx routes available for Surrey Group challenge walks for the first time and are having a few teething problems. The Punchbowl Marathon route was plotted in Tracklogs, saved in gpx format and made available as a download.

However, some PBM entrants are having trouble opening the file in their mapping software after downloading. As far as we know, this happens only with Garmin Basecamp. This can be overcome by the user sending the gpx file direct to the GPS unit, then if necessary, exporting to Basecamp from there, but this is cumbersome.

As other groups must have similar experiences, can anyone offer advice on how we can prepare/manipulate/de-glitch the gpx file before upload so that it is more user friendly? On another post on the forum, compressing it with Winzip was suggested. Obviously the user then has to de-compress it.
