6 Mile Pace Run

6 miles up at the lake, 1 mile warm up, 1 mile cool down, 4 miles at pace. Took one walk break before the pace miles, one 30 seconds one during, and one after the pace miles. 56:06 for 6 miles, 9:21 average pace, splits of 10:17, 8:58, 8:58, 8:58, 8:58 and 9:53. AHR of 158, though it was creeping up the final pace mile. I'm glad I didn't have to run more than I did, wasn't all that easy - very muggy out. 79F with a 72F dewpoint, so sweat was just not evaporating.
