Not wishing to be pedantic, but Scald Law and Alva are in Scotland.
Taking into account parking, facilities, course for championship races:
Sedbergh, Pendle, High Rigg, Wansfell, AW, Viking Chase, Shutlingsloe, Coiners, 3 Shires, West Nab, Dodd Fell and with apologies to organisers, probably many others I've forgotten.
However, I refer to previous posts on this subject; we rely on the goodwill, energy, and time of landowners and organisers, so together with other considerations such as geographic spread, championship races are and have to be rotated. Regrettably, the increased popularity of junior running means that a lot of venues are no longer suitable as it is difficult if not impossible to provide parking and other facilities.
Keep building the list.
