What counts as a day of rest? Some training schedules require that you take one day a week and do absolutely nothing, but nothing? Not a walk, not yoga, not a ten minute ab video? It's hard to determin what constitutes rest. Is it just a day away from running, or is it a day of complete sloth?
Today is my planned day of rest, and in some ways my body needs it -- Sunday I ran 5 miles, Monday I did arms and yoga, and yesterday I ran five miles, so I'm a little stiff. Yet, a part of me finds it difficult to take a day off. I feel guilty for some reason, and feel completely unjustified eating that piece of cake. At least when I ate the cake yesterday I could say, "It's alright, I ran five miles this morning."
