I've just got the kinvara tr2's. After searching for a road shoe for ages ending up getting these for light trails, roads and gym. Fine for all of those things. Given them a little bit more punishment in the mud but weren't great. Sticking to my new balance 110's and 1010's for that kind of thing. Got the kinvara's in silver which look great and only paid 50 quid for them.
Chopwell woods are great for running. I often combine different combinations of the three marked routes in order to make a longer one. Aldo heading a bit further out along the Tyne valley towards ryton, prudhoe heddon and hexham there are some great footpaths and bridleways that can be turned into pretty hilly long runs. A lot of the long runs I do are adopted from mountain bike books. They obviously stick to bridleways and roads but just by looking at the maps of the area, you can substitute some of these for footpaths.
If you're willing to drive out a bit you can have some epic days out around slaley and Blanch land, and all this even before we get to the Cheviots.
