I actually woke up early enough to go swimming this morning and could have gone, but I made myself roll over and doze for another 45 minutes or so because I know if I swim too much too soon, I'll injure myself. The last time I ramped up the swimming too fast, I injured my arm and couldn't do anything more than kick for a month or so.
Yesterday was Masters swimming and we had a good workout. The middle set was 3 100s, 3 200s and 3 300s. I thought I would be dead by those 300s (12 laps for the non-swimmers), but I actually felt really energized. We had a new guy in our lane and I noticed that when I went first, he was on my feet for the first few laps. So I let him go first, and realized that he's fast when he starts, but then he loses his steam and I am right on his feet for the last several laps. It's good to know I can keep an even pace. That will be a good skill for the swim in September.
One thing I forgot about swimming - by 10:30 or 11 PM, I am OUT. I get up at 5:45 or so, swim, then feel pretty energized all day. But after 10:30, I am absolutely useless and can't keep my eyes open. It's pretty sudden and really annoys Jason when I drift off right in the middle of a conversation with him (which has happened before).
