16 Mile Long Run

16 miles up at the lake. Wasn't as hot as last week, but it was sort of a building heat, and it was very humid. Got started at about 7:30, about 79F out with 70F dewpoint. When I finished shortly after 11, it was around 85F with a 71F dewpoint. It tried to rain a few times, but it never really got going, mostly cloudy. Was planning on doing my pace setter marathon pace the whole way, but my heart rate started creeping up a bit too much after about mile 10, so I had to slow it down and take more walk breaks. 3:05:26 total time, 11:35 average pace, 160 AHR, splits of 11:14, 11:12, 11:19, 11:06, 11:02, 11:08, 11:14, 11:09, 11:07, 11:10, 11:51, 11:55, 12:01, 12:10, 12:57 and 12:43. Was beat by the end, and a sloppy mess. Brain felt a bit mushy like I had ran farther. I have a few more weekends to work on the pace, hopefully one of the weekends is a bit cooler.
