Run For Your Lives

I'm going to sign up for "Run For Your Lives" in Illinois. It will be my first "5K"...But, it's also an obstacle course (Tough Mudder, Spartan Sprint, Rugged Maniac type of thing)...where you get chased by zombies. Anybody else interested? It's not 'til 9/21. My boss suggested it. I think we're shooting for the 11 AM wave.   http://www.runforyourlives.com/illinois-overview-2013/
