Like you I am also serving - Royal Signals though. I dont know if you are into Ultras, but a few people are looking at setting up an Inter-Service Ultra competition. If this does take off in some way then there is the possibility to get Fell Running accepted as a strand of Army Athletics.
All the best mate and you certainly have some cracking running grounds that you have mentioned.
Inter-Service Ultra sounds good, i'd deffo be interested in that!
