A Wall of Cold Air and a 10 Mile Tempo Run

70 degrees inland, however, it must have been 50 degrees by the lake.  There was literally "a wall of cold air" extending about 200 yards westward from the lake.  The temperature difference was radically different between the west and east sides of LSD. Anyway, ran 10 Miles @ 7:17 per Mile:  Splits:  8:19, 7:31, 7:08, 7:09, 7:33, 6:44, 6:48, 7:11, 7:45, 6:42.  Final 5k: 22:25.  With these good splits, it looks like I can now put my race results from Sunday in a shoebox and bury them in the backyard.
