good swim workout

While I'm not really in the habit of posting the details of my workouts, I liked the way this swim went, and since it's kind of a benchmark workout I figured I'd post it for posterity. I'm not swimming much, maybe once a week. I am trying to up that a bit but since I do it ad hoc I don't have a schedule to fall back on when I don't feel like swimming. So I blow it off. I usually make up my workouts on the way to the pool. Typically I have a 2000 yard minimum and 2100 maximum - sounds like another barrier I need to break through eh? Today was 2,200 yards (!!)with 500 warmup, 500 with a pull-buoy and paddles, and then 10 x 100 descending splits and 200 warm down. The pull buoy 500 was good, I was shooting for 8 minutes and did it in about 7:45. The 10x100 was tougher. I had to remember to go easy on the first one, last time I did this I started at 1:31 and couldn't really do much better. Here are the splits:
1:39.0
1:37.7
1:32.5 (I lengthened my stroke here and went faster without much effort - interesting)
1:32.46 (still going down, if barely!)
1:32.08
1:29.1
1:28.1
1:26.2
1:25.2 (cranked up to 90%)
1:23.2 (gave it whatever I had left)

Just over 1:30 for an average.

Pretty satisfying to see that progression.
