If it's Wednesday, it must be intervals

Got on the trainer yesterday morning and warmed up and started to do these alternating 1min intervals real hard / sustainable / real hard/ sustainable power, and was feeling like garbage.

Then realized that I was supposed to be doing recovery zone 2, not intervals. Ahh. Not with it lately wrt training. Just not into it. Today did the alternating intervals on a hill climb. That was pretty fun, but didn't prepare right foodwise, and went into it with low energy. Like I said, not into it.
