have you not worn out the porter valley yet?
I'm pretty sick of it and I've only run down it twice this term...
You'd be surprised how much Porter valley has to offer if you explore the southern slopes, loads of little paths to discover.
I have a few paths I alternate between, if I went other places it would mean more road running. Also easier to compare one run with another if I run them over the same route.
Still don't think I've found all the little paths, just the other day found a new bridge over the river/stream
