Any rides for beginners?

Thought I'd bump this thread with a question. What route(s) would people recommend for somebody (me) that's not really ever done anything longer than going the long way home commuting or doing a few laps of parks? I was thinking fairly short - maybe 25 miles or so (round trip), starting from centralish London. Would be nice if it's possible to get away from traffic and maybe get some pretty views in, any thoughts?

edit- routes for solo rides, not ready for group rides yet!

Which area do you live in? There are various convenient destinations by train from where you can start. Check out the Tuesday Night Ride Club routes list:

You're rather spoilt for choice there. :) These are all slightly longer than what you want but there's a lot of variety--hilly, flat, moderately hilly.
