I have a marathon/half-marathon to run in less than a week (Sunday, to be exact) and I don't have the mental strength to make it through 3 miles anymore. My lack of appetite and inability to sleep when I am exhausted are probably also not helping at this point.
So tonight's crappy workout was 3 terrible miles at the indoor track at the school gym followed by a piddling 15 minutes of the Minna Lessig workout. I can't remember the last time I ran more than once a week, and I also can't remember the last time a run hasn't ended in a feeling of complete defeat accompanied by a generous amount of tears.
A word to the wise: don't sign up to run a second marathon after you have just finished running your first unless you have seen the future and you are sure it is something you must, absolutely must, do. If this is not the case, do yourself a favor and take a break. Otherwise, you risk dealing with what I am dealing with right now, which is to say a complete lack of enjoyment from running (something that you once loved more than life itself) and a profound sense of burnout and failure.
