The usual way to download the GPX file is to "right-click" on the link to the file, then sellect from the menu "Save Link as" example: Annapolis Valley West GPX file
The tool for creating a map showing the track from GPX files is Map Input. There are numerous options including choice of background maps.
There are fewer options than the full GPSV set. On the left is a "zoom" (map scale) control. On the top right is a menu for choosing the backgrounsd maps: the most useful are the GoogleMaps, OpenStreetMaps, OpenCycleMaps, and Toporama.
If there are multiple tracks on the same map, a list of them appears to the right. Clicking on a title makes the track disappear and appear.
