I think it was hiding, but I saw a little of it during my recovery week last week. Today, it was definitely there. Today was my longest swim yet, and made my goal of a 10,000-yard week actually seem attainable, although I don't think it's going to happen this week. Either way, my arms are about to fall off.
The main set was 500-400-300-200-100 descending, which I was able to do, and banged out a 1:25 (!!!) for the 100. That was followed by 2x400, which were really boring and long, and I finished up the main set with 5x100 at race pace, which I was also able to do descending (1:35 for the first, 1:29 for the last). Go me! I figured my 5x100 would be somewhere around 1:42s, so I was totally psyched to see a 1:35 for the first, and at a not-crazy intensity level. At that point, I figured I should really go for it for the remaining four. Let me tell you, I have never felt lactic acid in my shoulders like I did during the last 2 100s. Ouch! But I was able to get the times I wanted, which was great.
I don't think I could have designed workouts on my own that would have gotten me to this point, much less getting me to this point in April. Hopefully this will all translate to faster race times.
Getting faster + not having to come up with my own workouts = getting a coach was a good idea. Hopefully.
