More Interval Avoidance

Seems like I'll do anything to cut intervals short. And this time bad math was involved. I'm planning on running tomorrow morning with the wife and kids, so I decided on my fourth interval that I didn't want to be worn out for that session, so instead of six intervals I did four. And somehow in my mind the warm-up and cooldown plus the intervals added up to 5 miles. Only when I was about done did I realize it all added up to 4.5, which is the first time in exactly six weeks that I've done less than 5. Today's lesson: don't try to do math when running, because apparently my brain can't handle both tasks at the same time.
