I swam today, my first workout in over a week.  Good one, too.  I swam a half mile all at once, no breaks.  took me 20 minutes and 20 seconds, which is my fastest half mile so far.  Unfortunately, I pushed myself a tad too far.  I was going to try to go a full mile today, but after pushing hard for the first half mile I couldn’t go on.  I tried doing a warm-down 1/4 mile with extra pushes off the side of the pool, but after doing 100 yards I just couldn’t continue.  So I did a float-on-my-back lap as a final cool down and left.
