7.3 miles on the treadmill this morning. Woke up and it was 7 degrees and super icy outside--no thanks. So opted for the 'mill. After 2 miles of warm-up, turned up the speed to 8.6 (6:58/mile) and held that pace for 3 miles and then upped it to 8.8 (6:48) for the fourth mile, and then did a one-mile cooldown. Felt good.
