Notes
1.5 mi warmup @ 5.7 mph, 2x1000 @ 7.5 mph w/ 4 min recovery @ 5.4 mph, 2x1000 @ 7.4 mph w/ 4 min recovery @ 5.4 mph, .93 mi cooldown @ 5.6 mph to total 6 miles.
Gym felt very hot, treadmill felt faster than normal (either treadmill wasn't calibrated like the others, or my legs were having a bad day). Had to slow the second two intervals down a notch, they really took a lot out of me today.
