Water Makes Me Tired

Had quite the tiring workout in the pool today. I could tell during the warm-up that the distance swim wasn't going to happen today and I was right. I did manage to get in 2 200s, though. I did that last, hard 50 before the warm-down in 37 seconds, which is my fastest time so far. Put me on a block and if I managed a flip-turn I bet I could break 30 seconds (again, great for an 11-year-old). Still, I'd like to do it from within the pool. Gimme another month. Managed to squeeze in 1600 yards altogether; 100 more than usual. Was very tired at the end. Makes me wonder if I should be pushing myself so hard. Tonight I will be starting a new book I bought on swimming so I hope I will find out.

FWIW, here was today's workout. It is pretty typical:

2x50 warm-up
1x200
4x50 on the 1:30
1x100 on the 2:30
4x50 on the 1:30
1x200
4x50 on the 1:30
1x100 on the 2:30
4x50 on the 1:30
Fast 50
50 warm-down
