First 800 Intervals of 2007

I ran 4x800 intervals this morning and I sucked. My average heart rate was 133. I can forget about going to 40 mi per week until I can get that average up to 145. I just went through the motions today seeing as how it was my first 800 repeats in 9-12 months. Now I'm worried I'm going to slack off on Thursday's 2 mi threshold run. That should have an average heart rate of 137. The poor showing today means I'm going to have to stay at 4 mi for at least another week, but probably another 3 weeks until the Frederick 5K on Mar 17. I now plan on going to 4.5 mi/day afterwards.
