I live in Blackpool (for my sins...), so most of my off-road riding is round the Yorkshire Dales, the Lakes, or good old Calderdale. I've also got a couple of fixie road bikes (both On-Ones, natch) so trundle around the local area quite a bit on them.

Sorry to say I've never actually ridden in Wales - my friend's got a caravan in Machynlleth and we've been intending to get down there for a weekend's riding for ages, but now she's living on Lewis it's a bit of a trek for her (though on the plus side, that does mean I've got a place to stay any time I want to visit Callanish etc. :-) ). And I really would like to ride the Brecon Beacons sometime too.
