Having done many obstacle (Tough Mudder, Spartan, Warrior Dash, etc) races as well as themed 5k and 10k races, I was SO impressed with how well organized this race was. Check-in took no time at all, their method of releasing racers continually prevented backups at obstacles and the event was just plain fun.
It allows more athletic people to try to complete each obstacle cleanly (the red balls were nearly impossible!) while allowing virtually anyone, athletic or not, to come out and be silly and have a great time, We had a group of nine including a couple people who never do ANYTHING like this and everyone had a blast.
Highly recommended.
