London's Toughest Hills

I live in Forest Hill and have found a back way all the way to Old Kent Road that barely goes near a hill...

The annoying is your somewhat restricted speed cos its back streets...

I have a route up from Como Road (small world!) that avoids hills; up through Crofton Park, Brockley and New Cross Gate and then OKR. It's a whisker over 8 miles to my work but the extra distance is easy compared to the hillier routes. On my way home I sometimes go over Herne Hill and over College Hill and down through Sydenham, sometimes over Champion Hill and through E Dulwich and up past the Horniman.
