Glad to hear that GG and I aren't the only ones. We did a 360 degree error there last time we tried (don't ask).
The signage is adequate up to that point, but then it just disappears. I think the local chavs have stolen the ones in Gleadless Valley because you can see the posts. But I've found a map of the last bit now so hopefully next time I can complete the route!
Let me know when this "next time" is.. I'd like to play
Quite fancy it myself especially if you are going to run at that sort of pace again so that I can keep up!
If by any chance you decide on Saturday not Friday then let me know....
