I'm a fairly recent returnee to running - but being up on the moors early this morning, minus one degree, sunny, only a slight breeze, just me and my dawg - well, it was great. I found the recently churned but now frozen mud to be a bit of an ankle turner, but it's a laugh running along wondering wether the frozen bog/puddle will support your weight or (frequently!) not. It was really great, and if I wasn't working tonight, I'd be up there again tomorrow early.
