There's a few hills to be found!

I had a quick knock up on google maps. This is a couple of roads I know close to where I live, going through St Ives, and then south around St Neots, and then onto the B660 north. It's only about 2ish hours.

I'd be interested to hear of other routes people know around the area, and then we could link them up perhaps. There's gotta be some good roads around Thetford Forest.
