Feature Requests: Map ALL rides on the Google Map at once

Hi,

I want a nice view of all the roads I've ever been on so I can see how much ground I've covered.  Is there an option where you can choose to display all the routes from all your rides on one Google Map, instead of just being able to display one at a time??  If not, then they should add this! 

Right now, I copied sections of Google Maps onto a Photoshop file and then highlighted all my routes onto there, but this would be a much better way to share.  Any suggestions anyone?

Thanks
