This is a nice route around Hartpury. I ran it once to recce it (which was needed, as there were some tricky parts to navigate), then went for it on the second loop. Parts of the route were a bit overgrown, and it is a shame that it is not walked more. I caught my ear on a bramble the first time round, and watched out for it on my second lap, but it still caught me on the forehead. Some of the local farmers must not be too happy about the footpaths/route as many of the gates were tied shut, which slowed me a bit, but not too badly. I thoroughly recommend this route (as long as you do not run it faster than me!). Starting and finishing at Hartpury, gives a good post-route drink/feed at The Royal Exchange.
(I ran alone, did not take food or drink, or buy anything on the route.)
