I take off one day a week. Usually on those days I don't wear a running watch and I don't wear running shoes. Not because I don't want to be reminded of running, but I just think, 'Okay, today you're a normal person. Don't stretch, don't roll on a golf ball, don't ice, just be normal.' Taking that one day a week keeps me in check and reminds me that there's more to life than competing in marathons. Also, when I know that off day is coming, I can push myself harder in training on a day-to-day basis. Because I know I'm getting time off in a couple more days.
