South London hills

Went out yesterday and found a few new hills to me, not exactly sure which road it was on but between Cudham and Downe. Out of Cudham left down some mega hill marked 25% then back up another I think it was Hang Grove Hill looking at the map. Neither were very long but both pretty steep. Glad I was going down and up the 25% though. Anyone manged to get up the 25% one into Cudham fixed?

It's not too bad fixed, as it's very short, and you can ramp up your speed a bit on the draggy approach.

It's more fun to ride down for that rollercoaster feeling as you turn off the Cudham road :O
