I only have a very rough itinerary that consists of riding Redlands between 11am - 1pm, Leith Hill between 1pm to 3pm, then Ranmore between 3pm - 5pm. But this is all open to rejigging on the day. I'll probably be driving down that day and parking near Dorking train station.
If you have to leave at around 2pm then you should be able to get back on either Coldharbour Lane or the A25 from Leith for a direct road route back to Dorking.
