Good going, Crankin! I am sure that was some strenuous running, with the hills. I have an almost dead flat path to run on here, just a slight bit of grade. I like it, though, as I seem to be so injury-prone, and running hills, up or down, would seem to make injuries more likely. Hope you don't have any bad after-effects. Just don't do too much, too soon, since you haven't really been running. I have made this mistake before. I am trying to avoid yet another injury by not doing that again!
