When the Insane Inflatable 5K comes to the University of Maine in Orono on Sept. 19, we want you to be ready.

A lot of you have asked us what it's going to be like bouncing through huge inflatable obstacles. We thought it would be easier to show you than try to describe it. Words just don't do it justice.

If you haven't registered yet, don't wait too long! Some of the waves are already filled up and you can save $5 if you register before Sept. 4, 2015!
