Cob Lane is liberally coated with "up". The climb out of Ardingly Reservoir is also character forming. Early on there's a bit that takes you by surprise, somewhere near Buxted, or at least it did to the bloke in front of me a few years back as I tried to whizz up it after whizzing down towards it and he made a mess of his gear change, causing me to grind to a halt.
(Ditchling Beacon is only on the Hillier)
