This morning was my interval run -- this time 4 x 800's on the 3:45 with a 200 recovery in between. I don't have my HR stats with me but I remember my times. Basically, I know that I am running these too fast but do not know pace well enough yet to regulate it because I am so worried about not making my interval. On alternate weeks due to my work schedule and the darker mornings, I will do some of these on the treadmill and that will help keep me on pace.
