Notes
I started out a little bit too fast. Stopped at the first mile "post" and adjusted my pace. Actually, stopped briefly at each milepost. The return half seemed harder than my previous runs on this course, I think because this was the first time I had done 8.5 miles two days before. Knees and other parts feel pretty good now - rightfully tired. Extremely glad I switched shoes.
McMillan says this equates to a 4:04 marathon. I think I can achieve a sub-4:00 marathon by May 3. Probably not a BQ.
