I did have a pleasant surprise; as I was heading up Heading I saw Tracy just prior to mile 2 of my walk. So I joined her and we did miles 3, 4, 5 together.
1:58:28 for 14:47 mpm; note the 15:56 and the dip/increase in the heart rate right around the time I had a 15:56 mpm average mile; that was the cemetery hill. The 3 miles with Tracy were just a bit painful for some reason; the pain settled down when I walked on my own and before..I am sure it is posture related in one way or another.
