Raining and humid (dew point 69, temps in 70s). Did a run to and around lake B and back. Ugly slow after about two hours trying to keep under 145. The 5.22 miles out was 56:23 (10:48 min/mi). The same 5.22 miles returning was 1:12:03 (13:48 min/mi) with lots of walking. Ouch! Not only that, but I didn't feel well. I think I was dehydrated.
