Swimming Morning Confusion

This morning's swim workout was supposed to be this:

250 warm up
6 x 25 drills
5 x 150 (50 easy / 25 hard) (:15 recovery)
4 x 50 sprints (:20 recovery)
6 x 25 kicks
250 cool down
= 1750 yards


But for some reason (and I even went over it in my head and counted up the yardage before I got in the pool) I did this:

250 warm up (correct!)
6 x 25 drills (correct!)
6 x 125 (50 easy...except 50 easy twice in a row / 25 hard) (:15r)  (EERRRNT!)
6 x 50 sprints (:20r)   (EERRRNT!)
6 x 25 kicks (correct!)
250 cool down (correct!)
= 1850 yards

So for some reason I just got the main sets all mixed up. Sixes were in my head. And when I went to do the 150s, I even thought to myself but how can it be 50 easy 25 hard...did I really see 100 easy?  And those sprints!! I was dying by the 5th, and took a bit more rest before the 6th.

I guess I'll need to work on memorizing a bit better before leaving the locker room, geesh. I only went 100 yards more, but I didn't do the 150s right and I did 2 extra sprints. I would have liked doing the 150s in the format they were supposed to have been done. And it would have been interesting to recover on 50 after going hard 25.

Anyway...... not a big deal. I just find it funny that I can't seem to keep swimming workouts straight. Maybe I need to laminate some cards.
