Notes
I did the first 6 miles easy and then ran the last 6 at a medium effort. I felt strong the last 6 miles. I would have run faster if the legs were 100%. I made an effort to push the last mile which was tough because legs were cramping, against the wind and that tough steep short hill in the last 400.
First 6 @ 8:28, 2nd 6 @ 7:25.
