5 Mile Tempo Run

5 mile tempo run, all miles at tempo - no warm up/cool down. Wanted to run a little faster than my marathon pace, but didn't want to push it too hard, run felt pretty good and I'm feeling more rested. Was a bit warm out, in the 70s and humid, but didn't feel too bad. 46:56 total time, 9:23 average pace, 158 average heart rate, took one 1 minute walk break at the half way point. Splits of 9:28, 9:19, 9:26, 9:25 and 9:15, so fairly consistent.
