London to Oxford route

[Moda]

Am planning a ride to Oxford this weekend and was wondering if anyone had a cycle friendly route that I can input into my Edge.

Have found a couple of routes via the web but would value the assembled wisdom here.
Thanks

Rather depends where in London you start from..... but this route from Richmond is pretty good, mostly quiet road and scenic.
