Swim practice. 200 3-pull-n-roll warmup, 10x100 on 2:30 (coming in on 1:40 because 50 seconds is a LONG rest :-)), 10x50 on 1:00 (coming in at 0:50, which was annoying because a 10 second rest is almost counterproductive), 2x(50 pull, 50 kick), 100 cooldown. But this was only 2000 yards, so I decided I needed more... NO SLACKING! I did 8x25 butterfly, and 50 breast. 2250 total. My butterfly was much better than in the past. my first 3 25's were all done in 8 pulls. I dropped to 9 pulls for the next 5 25's. But the fact that I was able to complete full 25's at all is an improvement. I've got to start pushing my fly sets out to 50's, then doing full 200 IM sets. That should be a hoot!
