As you aren't, the main reason to go to Newlands Corner would be that as it has the large if rather slow serving cafe and picnic benches there it's a more natural furthest point of your ride. It also adds some climbing to your stats and has a nice view across the Surrey hills.
I'm struggling to get the file at the moment but if you have Garmin the route I would use is here.
Fair enough, I assumed you were a Surrey veteran.

It's pretty much on the NDW, right next to the A25.
