Game On!

I am registered for the Seafairmarathon. I know I am crazy...and perhaps not totally ready, but I want to see where I stand. Shooting for a 3:10 but would be happy besting Boise. Planning on making one decision at mile 13. Go for it...or training run. Once made...have to stick to it. I don't want to over do it if I am really not ready, but I don't want to second guess myself once I decide to go for it. Wish me luck!
