Hebden's got everything that a "tree-hugger" could want... poetry recitals, craft shops, lesbian-friendly clubs, arthouse cinema and vegan cafes etc... It's not all idyllic all the time, as it can be a bit chavish at night in some of the town centre pubs.
Heptonstall and Old Town sit above Hebden and there's some lovely villages going out of Hebden near Mytholmroyd - Booth, Luddenden, Midgeley - but cheap they aint and they're not as lively as being in Hebden. Mytholmroyd's got some rough areas, but if you got a spot in Cragg Vale then that's a great place to be based. AG would have a fair commute to Bingley if you settled in any of those areas. Oxenhope would be a good place in that respect, but its a car ride away from Hebden and, again, it's not as lively as HB. All the places i've mentioned would give you (or AG) very quick access on to the moors, fantastic scenery and great running.
As for training, CVFR are based in Mytholmroyd: billj, stringman, weetabix power, gaz, gaz77 and me are all CVFR members. There's Tod Harriers down the road as well but why would AG want to go there when there's CVFR?
