I've done others, Warrior Dash, Gladiator Assault Challenge, and some more regional ones, but not the one you're mentioning. I always had fun until they became too popular and poorly managed. Waiting 20 minutes to do an obstacle? Not fun for me anymore. My son and I will do a few this summer. I do like them if they are run correctly. Let us know how it goes for you. I'm gearing up for my first half marathon of the season. Good luck and have fun.
