Another one down

4 by 800m runs with three minutes rest at 80%. Did the first two at around four minutes and got carried away on the third as that one went off at 3:45. Slowed the fourth one down to 3:55. Did some running drills - wall drill, posture drills, running in place and hopping. Attempted good form on the 800s. One thing I am trying to be cognizant of is not straightening the leg - I'm pretty sure that is the cause of my knees aching on the long runs. Will be running 13.1 miles in the rain tomorrow - have the alarm set for 5:30 a.m. (rain supposed to be heavier later in the day so it does not make sense to try to wait it out.
