you want to go along military road out of rye, to appledore then up reading st hill (the only hill and fairly easy) into tenterden, then biddenden to headcorn. It's a bit longer but quicker and a really pleasant ride.
Allow 1.5 hours to do it fixed, and add an extra 15 mins if it's a slow group or you expect flagging/punctures. Trains are on the hour, direct to London's Famous london. you don't want to take the one going back to ashford.
not that route Sam!
it'll kill you off.
