Day 4^2(lne(4X)+7^4)

No miles today... had to study and take a math test instead. I always vowed I would never be one of those people that "doesn't have time to exercise", but today that happened. I was due for a "recovery day" I suppose, however, 6 hrs of grueling mathematics is anything but re-cooperative. I feel like I just underwent massive brain surgery! Talk about worst trade off ever, running: one of my favorite things, and math: makes me cry like a baby. As long as I can figure what it takes to achieve 26.2 miles per 9:00 min./mile pace, I'm set, and all I need for that is shoes and a watch... okay fine and maybe a little math (:
