Started out at what I hoped was a sustainable pace, but some incipient pain in my left leg soon disabused me of this notion. I did take in the hill on the way out, so got a little actual exercise even without going very quickly: it's a steep hill. Once around the pond, so as not to push my luck on either the legs or the knees.
