Notes
COMMENTS: What a pace! I felt good all day and started out strong but didn't realize I had such a fast pace until about 1.5 miles and noticed the HR a little higher than usual. I knew I was in trouble when I reached the half way poing at 19:50 and my HR was already at 160. The last mile was a real struggle. Thats where most of the zone 5 came from. Tomorrows run needs to be easier.
