Wed 2/24 - PM 55 minutes incl. 4x1600

20 minute warmup on the treadmill, raining cats and dogs. 1600s of 5:34.8, 5:33.7, 5:33.6, and 5:30.7 with recovery interval around 80 seconds between each. Slightly negative split on each one. I would have liked to do six reps, but desperately tired all day after getting to bed quite late last night. Cut the cooldown back significantly in favor of stretching which has been neglected of late.
