I stumbled on this excellent site. It is a forum where you can upload and download maps of tour routes that others have ridden in your area. This link has rides for South East Queensland in Australiabut you can use the search engine for your local area.

Cheers

You're right, it's a cool site. I added a route for one of the rides I do here in South FL.
