5 Mile Speedy Run

Got going fairly early, 66F or so out, humidty wasn't too bad. Felt pretty fresh so decided to push it a bit, running 5 miles in 45:35, avg pace of 9:07, Splits of 9:51, 9:03, 9:16, 8:46 and 8:38. Avg Heart Rate of 164, with last mile avg of 172. Will probably avoid running hard until after the Chicago Marathon.
