Downloading tracklog to device?

Some of the guys have put up their tracklogs from the Saturday Swinley shebang, and I’m trying to work out how to get it into a form I can use next time I’m there to find trails etc.
eg Pants has put up a tracklog from a Garmin Edge that uses Google Maps to show the route. I don’t have an Edge, but do have a Forerunner, which can do basic ‘find this location’ jobs; I also have a phone with GPS and Google Maps installed. ( http://connect.garmin.com/activity/1760946)
Can anyone talk me through how to get the route onto either of those? I’m struggling somewhat….
