Thanks again for that Ergie. The one decision I have made is to follow your advice and cycle down to Victoria station from Euston. As I'm doing that I was thinking I may as well stay on train to East Grinstead.
I think that would be a mistake. East Grinstead to Newhaven is tough going on a laden bike, and you have a lot more map reading to do if you take the Horsted Keynes route. I'd go to Horley and head for the B2036 southwards (come out of station, turn right, go 200 yards, and you're on it) before glancing off to Turners Hill. This is a long drag up, but not unpleasant. From Turners Hill you swoop down to Ardingly and Lindfield, then fork left at the post office, take a right/left at the A272 which takes you to Wivelsfield. Turn left and just continue on, ignoring siren calls from the DfT signposting left turns to Lewes. The road you're on goes pretty much in to Lewes, and, having gone through Lewes (which will require a sketch map - the signposts aren't good), as others have suggested, keeping west of the river down to Newhaven is really very pleasant - you even get a sweet view of the town (or the sweetest that is possible bar going to Aix-en-Provence instead) as you come in.
Other people have suggested that cycling through South London is a trial. Well, they're wrong. Cycling through South London is like going to heaven. It will put a song in your heart. And, if you think you can stand the joy, I can give you a simple route out to Horley which you'll be telling your grandchildren about.....
I like the Woldingham School route for some things by the way - it's an excellent night time route, but the roads south of the A25 can be icky.
You could take a through train from Watford to Gatwick, and this can take you to the B2036, but you need to know the Schlumberger car park trick....
And - if I'm free, I'll pick you up at Euston and take you down to Newhaven. I'd reckon on adding an hour to your usual time for the distance.
