Planning to train for a marathon

I know that training for a marathon will be exhausting. But planning the training makes me want to puke.

A week after registering for the Milwaukee Lakefront Marathon, I slipped on the ice and threw out my back. I finally got permission to start running 1-2 miles a couple times a week and then Friday I slipped on the slushy snow as I was getting into my car and sort of tweaked my left ankle/calf/IT band/leg/etc.

CAN A GIRL CATCH A BREAK?!

Tonight I mapped out my training plan, starting with October 7, and working backwards for 30 weeks. I am merging three different Hal Higdon plans.

I have also realized that I can’t safely train for the Wisconsin Half Marathon in May, as I was planning to do, so I’m pushing back my first half marathon of 2012 to the Summerfest Rock ‘n’ Sole (Plus, the week before, I’ll run the equivalent of a half marathon during Ragnar).

Then, in July it’s the Chicago Rock ‘n’ Roll Half Marathon… followed by possibly the Madison Mini Marathon in August.

Enter the most hellish month of my life ever:

Followed by a marathon and epic rest week. #dontdie

I can’t be the only person who freaks out and requires insane planning before a race… What do you do to plan for a race?
