This walk's different from most of the "there and back" ones I've posted because I went counterclockwise, as indicated by the mile markers. I didn't realize it when I set out, but going this way means a lot more uphill walking. Long chunks of it, rather than a couple blocks here and there that are really steep. It was extremely challenging. The good thing is that I know now that I can make these walks more difficult in the future if I find they aren't challenging enough, just by going the other way.
