Mission accomplished

I set a new PR for 20 minutes tonight: 5627m for a 1:46.6/ 500m pace.

I did lactate threshold testing last weekend, and have been training with a new strategy of working within certain target heart ranges for the prior month. Trying to build my aerobic efficiency, so that it takes longer before I go anaerobic, and that when I do, I'm at a higher power output level. I've added longer, lower intensity work to my mix. And it seems to be working.

I think there are still gains to be made. 2007 will be a good year, as long as I don't injure myself.
