Today's workout was not about speed, just survival. I felt slow after several days of pretty hard swimming, so I thought I would do an "easy" workout...straight forward, not too challenging physically or mentally. 50 x 100, which ended up kicking my butt. I decreased or increased the interval in step-like fashion after every set of ten, expecting my 100 times to get faster.

10 x 100 on 2:00 (mostly around 1:40)
10 x 100 on 1:45 (mostly around 1:37-1:40)
10 x 100 on 1:40 (1:34-1:41)
10 x 100 on 1:45 (1:39-1:44)
10 x 100 on 2:00 (mostly 1:40)

5000 yards in about 1:35.00

I think 1:36-1:40 is my aerobic pace; 1:31-1:34 is closer to my threshold pace, and 1:27-1:30 is probably my vO2-Max pace... that's my best guess right now; so this was definitely a pure aerobic set, though I intended to have some threshold work and even a few reps at my VO2-Max pace too. It just wasn't happening today, so I guess my body is a little worn out. I think I'm going to try this workout next week too, to see if I can't improve the times... eventually even drop the intervals further.

I usually like working in the aerobic range, but this workout just seemed unrelenting in a way that repeat 1000s don't even seem to be. I guess it took me by surprise, given how easy it looked on paper.

I finished July with more than 360 miles YTD. Since I started swimming again in January 2011 (17 months), I've logged just a bit more than 700 miles in the water.
