Heh. I'd gone to Mum's by train, and stayed over the weekend, then cycled home on Monday.
It is moderately hilly - the stickiest being a 16% east of Dorking, which is where my hub started misbehaving, though the 12% near Riddlesdown also gave me problems, as I was beginning to get tired.
Devil's Punchbowl is nice - there are lots of lovely lanes for cycling in that area, and my sister used to work near Burpham.
CJ - I'm sure if you could do maintenance on a motorbike, a push bike should be easy peasy. I've been doing it pretty much all my life.
I got my brake pads and some lube from Halfords, and went for my trot. But it started to rain, so instead of walking home afterwards, I ran to get into the dry, and ended up doing 7km.
Ridiculously, 7km of running is probably more of an achievement for me than 55 miles of cycling.
