Wow, it is amazing how one can feel like they are the only one in the world with a particular problem, then find out other have it , too.
I have been training for a marathon for the last couple of months. I was a regular runner, but on the low end of the mileage scale. I am in decent shape and at an ideal weight, but I found myself 5-8 pounds heavier after increasing my running. Maybe I have been feeling the "I ran my *** off today, give me the girl scout cookies" urge.
I read something very interesting the other day. An article about the real crazies who run the 100-200 mile races across deserts and such. One woman, described why she thought women were better at long, long , long distance running. Her idea was that men are too competitive and try to crush their runs, instead of seeing each run as a building block. Women, she said, see their opponent in the mirror, so don't feel abashed at walking a little every once in a while. Also, in order to run those ridiculous distances, you have to be able to train for a long time, so really pushing yourself into an injury is truly counterintuitive.
I find I agree with that, and have tried to incorporate a little of that into my training runs. Just moving my body over the 9 miles I will do on sunday is a pretty **** good accomplishment. Once I get the mileage up, I will start paying closer attention to pace.
