Big Horn Trail Run 50 Miler, I'm getting scared!

This run is sneaking up on me like a homeless man on a half eaten sandwich. Before I know it I will be scooped out of the trash can, with his back to the street, I will be devoured. I am still pushing hard in my training, but the light at the end of the tunnel comes into focus, and when I think I have a firm grasp it slips through my fingers. This last week I ran 29.98 miles, 7 hours & 39 minutes, and 3,794 feet of elevation gain. Sounds awsome, but I fear it is no where near where I need to be on race day. This week I am going to push hard, and my goal with be to spend 12 hours pounding the trails in a week. I am going to be pooping down both legs on race day, if I know in my mind I can't eaisly handle 12 hours a week. I would feel even better if I could bump up to 14 or 15 hours a week in may. 50 miles, where do I get these crazy ideas. But, the plane tickets are purchased, the hotel is reserved, and my entry fee has been paid. Plus, I have never been one to back down once I started something. All the other goals of no meat, or running barefoot during the race seem insignificant, and above all else I must be prepared to run and finish the race.
