I found this neat site that alows me to share my rides with other riders it called Ride with GPS. It takes data from my Garmin Forerunner GPS and uploard the data to the site. You can view the route on Google Maps and it is just a neat way to share rides and keep up with rides. You can share the data on Facebook also. Here is an example from one of my urban rides around town. http://ridewithgps.com/trips/159298
Their web site is http://wwww.ridewithgps.com
They have just started the site and it is growing, I hope you will enjoy the site.
