5k Zombie Run?

I don't think anything could motivate me to finish a 5k obstacle Court like brain-hungry zombies. Well I'm in luck because from now till next year several cities across the country will have this type of race. Here is a description from their website:

"Runners will navigate a series of 12 obstacles throughout a 5K course in an attempt to reach the finish line — all while avoiding zombies. At the end of this adventure race, you get to celebrate survival (or zombie transformation) with live entertainment and music, local celebrities, vendors, food, and of course, beer!"

For my DC people, there is a race in Baltimore on October 22, 2011 and for my Boston people there is a race  in the city on May 5, 2012.
