Ready made 100 miles which included the TNRC Exdown hill and a few other lumpy bits - http://www.action.org.uk/route/225873 It's a circular route so you could start / finish anywhere along it.
I also did this route recently (Great Kent Ride) which is shorter at 60 miles, is less hilly and is a bit further out but it was a really nice route (IMO) - http://www.cycle-route.com/routes/Ashford_Loop-Cycle-Route-978.html
