Notes
pretty hard run in the sun. big hill really beat me up, especially the 2nd time up it. last mile was very difficult. too difficult for a tempo run. compared to last 4 mile tempo run on 2/7/08, this was a bit faster, but HR was much higher today.
4 miles (27:46 is about 6:56/mile):
6:50 167/176
6:59 172/177
6:46 174/179
7:11 176/180
