Cerebrun is the first obstacle course run where how far you run and how hard the obstacles are depends on how you answer mental challenges.
You can choose to run on either April 13th or 14th. I'm running Sunday at 11AM, but you can choose anytime that fits your schedule. To get more information or to register, go to http://www.cerebrun.com/.
