Tough Mudder in 3 Days

I am reading over my wavier for the Tough Mudder this weekend. They call it the DEATH WAIVER. Hehehe, uh scary. I am the strongest I have ever been and faster with endurance but nervousness is setting in right now. (That's why I wanted to do it. It is scary and I am tired of saying I am afraid of heights and other excuses.) Checkout the map of the course. You can hover the mouse over each obstacle for a brief description. http://toughmudder.com/flash_course_map/texas-dallas-2012/map.swf
