I have never done it because I just use the Garmin site with the information for my training purposes. There is software that you can download called Foreconv that will allow you to do it. Here is a website that gives some additional information..... http://gizmodo.com/221456/gps-coolness-downloading-suunto-and-garmin-forerunner-data-into-google-earth
Using Garmin connect, their free online service, you can view your run either in bing maps or google maps. You can also download your stats into excel or csv format using Garmin connect. If you are a member of the daily mile online service your Garmin data can be loaded up there as well. I hope that is the answer you are looking for.
