They only allow a certain # of people on at once. This was not the only obstacle that was broken, this is the only one that completely collapsed. This is a new brand/company that many in the racing community have never tried so a lot of us went to support a new player in the game. Normally at these types of races the people are extremely fit. Sure you have the HAES types that sign up but they are the minority at these races. I mean you can count on 1 hand how many big fats show up to the more well known and challenging obstacle races.  Look at the size of the people on the obstacle (Together they have to weigh about half a ton combined in just that pic), and those are the smaller fats that showed up. I've never seen so many Crisco mainliners at this type of an event before.
