This is my brain on marathon training....

I have to run today. Maybe I should run tomorrow instead. Make sure I drink enough water. How big is this water bottle? How many times should I fill it and empty it before I leave? Will that create too many disruptive trips to the bathroom? Did I have any salt today? Remember to grab some salt packets from the cafeteria. Darnit, I forgot the salt packets. Are my favorite running clothes clean? What's the temperature? How should I dress for this run? Is it too windy to run on the boardwalk? I hope I don't have to run inland, or worse... on the treadmill. I can't have any wine if I'm going to run today/tonight/tomorrow morning. Wine is about 120 calories a glass. That's 12 minutes of running. Ok, so I can have wine at the end of the week *if* I run at least ____ miles. Oh but I ate that cake. That must be at least 800 calories. So I need an 8 mile run to break even but my training schedule doesn't call for more than a 5 mile run this week and if I run more than that, I might be too weak for my long weekend run. So I just have to make sure I don't waste anymore calories. Speaking of weekends, I ate a lot this weekend, if I start gaining weight, I won't run as fast/strong. Did I gain weight? Look, you can't see my abs today. I must be heavier. Darn. So much for a PR marathon. But wait, all my clothes fit fine... but I feel heavier. I should carbo load for this long run. I need the fuel. But if I don't run and I carbo load, I'm just inviting the weight to pack itself on. If I lost 5 pounds, I could be more efficient at the marathon distance. I can't try and lose weight during training, that's nuts. I can't wear those shoes to work- they'll hurt my feet and mess up my run. But I hate being in sneakers all the time. When will I have ten normal toenails again? Oh, my knee hurts a little again today. I don't want knee problems. So many runners have knee problems. If I run tonight, I'll barely have time to make dinner for the kids. I should've planned what to make for dinner. If I don't run and make dinner instead, I'll be behind in my training schedule. I need to figure out what to do about dinner NOW. If I don't feed them before I leave to run, it will stress me out the whole time. My usual route is boring. I need a new route but what time does the sun rise/set? I can't plan a new route now- what if the new route has parts that are poorly lit? I don't want to sprain my ankle. I don't want this training run to be my last training run because of a silly preventable injury like that. Maybe I should run tomorrow instead. I have to run today...
