Are map layers and overlays included in GPX exports?
When you export a GPX file out of AllTrails, only those data points that are part of the GPX specifications will be included (specifically waypoints, routes, and tracks). Items like map layers and overlays are custom to AllTrails and will only work within the AllTrails ecosystem. As such they will not be included in your GPX exports.
