Brighton to Dorking

Hi, am going to do the BHF London to Brighton in June. I think it'll be a pootle down but I thought I'd bike back from there. Can anyone suggest some return routes, that are relatively 'friendly' - possibly well travelled by bikes, from Brighton that do not take into account Ditchling Beacon (it'll be mobbed with those heading south) and gets you in or near to Leatherhead?

You could either go to Shoreham along the coast on a cycle route, or go over Devils censored , which isn't too hard a climb from Brighton and you can go north ish through Henfield and on to Horsham on quiet roads. Keep to the east of Horsham town centre, go through Rusper and on towards Newdigate and then maybe head west over Leith Hill and on to Leatherhead from there.
I did it there and back one year, but went via Pyecombe (just north of where the A23 crosses the A27) and through Crawley. I wasn't as fit back then and it was a miserable lonely ride for about an hour as my energy dropped off completely.

As per DaveP1's comments, I've done this route from Brighton to Box Hill (and back) which will avoid the L2B route and goes up via . Once you get over Devil's censored (and it's not really much of a climb) it's pretty easy going all the way - a few ups and downs but nothing too challenging.
