Thanks for the kind feedback about the site Joe.
I'm afraid I'm not sure which format you would need - probably GPX Track. I think you would need to try both and see which works best. GPX Route files are generally for devices with their own navigation capability, so they only include waypoints for each new direction. GPX Track files contain all the detailed coordindates of the route.
Firstly I have to say what a fantastic site this is; really straightforward and easy to use.
I was wondering what type of file I need to download (GPX route or GPX track?) I'm using RideOn GPS which then sends direction info (arrows, text, distance etc) and notification vibrations to my Pebble watch. It supports GPX file but I'm not sure what type?
