London's Toughest Hills

I'll see you those 2 hills, and raise you a Chalkpit Lane, up out of Oxted, past the quarry.

Don't know that one. It's in Surrey you see. Going from east to west we have:

Sundridge Hill : 260ft rise in 2220ft = 11.7%
Brasted Hill : 240ft rise in 1775ft = 13.5%
Hogtrough Hill : 200ft rise in 1300ft = 15%
Titsey Hill : 430ft in 5000ft = 8.6% (although the steep section at the beginning is 10%)
Chalkpit Hill : 440ft rise in 3000ft = 14.6%

Interesting stats :0)

But to be honest, I don't know why I bother knowing about hills. Being 13 1/2 stone I'm fucking shit at climbing them.
