Macclesfield? Ah, that sounds promising: stay with my sister in Buxton, her hubby does an occasional tri as well. (swims like a fish, but bikes & runs like one too). And I'd get to drive the Cat & Fiddle on the way.
Romney Marsh? I know where that is. My wife is from Kent. We got married there. There's a nice view over the marshes, and on a clear day you can see Dungeness Nuclear Power Station. Is that 17th century too?
Middle Beaver? You've got to be joking, they might as well call it Lady Garden.
