When you make the decision to sign up for a marathon, you are essentially giving up a large portion of your life for one third of a year. Last year, my first, was hard. Adjusting to running five days a week, up to 22 miles at a time, was rough on my body, but not necessarily on my mind. Last year, I had the luxury of flexibility. I had lost my job just two weeks before my training was set to begin. If it was going to rain in the evening, I could get my miles in in the morning — and not just at the crack of dawn in order to make it into an office at a decent hour. I could do it whenever I felt like it, whenever the weather permitted. This year is a whole new ballgame. I once again have a relatively low-mileage schedule to make it easier on my injury-prone body. But the intense heat of the summer has forced me into 6:00 a.m. workouts or earlier, freeing up my evenings, yes, but leaving me so exhausted that I can do no more than throw together an easy dinner (preferably without an oven or extended stovetop-time) before I feel I can do more than sit on the couch and stare at something — with my legs elevated, of course — and eat ice cream.
