Herefordshire is actually very well placed for easy access to the very active Shropshire and South Wales fell running communities. Mercia and WFRA websites will have loads of helpful information for you. And you are not that far from real hard-nut stuff in North Wales and bog-trotting mid-wales events. All of these can be reached without having to endure the horrors of the M6 which usually has a way of totally ruining your weekend!
