Best Swim Test EVER!!!

I did a swim test yesterday.  It was a CSS test, which stands for Critical Swim Speed.  After 1200 yards of warmup I had 400 yards all out.  I had a goal in my head, and I went for it.  I pressed hard, needing to breathe every stroke in the last several laps.  My legs were going numb; I wasn't seeing straight.  I was swimming as hard as I ever had.  When I hit that wall I was all...

5:54!!!!  That's a 1:28 per 100 yards!!!  I have never been able to average under 1:30s!!!

Then I did another 400 yards easy and then it was time for another test.  This time it was 200 yards all out.  Again I went for it breathing hard, kicking and reaching, and swimming for all it was worth.  Eight laps later and this...

2:53!!!  Eff yeah!!!! 

Of course, now I have a threshold pace that scares the crap out of me and I have no idea how you even do threshold repeats with your head underwater.  For now, I totally won the gold medal.
