London's Toughest Hills

Not on nimhboid's route though.

Looks decent enough (hey, it even has an official OS viewpoint!), but cuts diagonally across the contour lines and has no arrows :(

Nasty for an A road, that's for sure.

yeah, i'm not sure of the exact route i took, as i deviated a bit in the last 1/3 of the journey.

but, bad enough for me, on fixed.
