The Insane Inflatable 5K is coming to Grand Rapids' Millennium Park this weekend, and we wanted to give you a sneak peek of some of the obstacles that you'll be, running into, sliding down, and bouncing through! Here are just a few of the inflatable obstacles for this weekend’s race. If you haven’t signed up yet, don’t worry, it's not too late! Hope to see you all there!

  • Big Balls

    It's not as dirty as it sounds. These big balls will bounce at you while try to navigate through this part of the course. This is pretty much the biggest ball pit in the history of ball pits. You'll have to be quick on your feet and pay close attention to make your way through this obstacle.

  • Disturbia

    This basically looks like a huge, inflated strand of mutated DNA. Disturbia will have you climbing and crawling as you work your way through it, and back into the light of day. It's not as scary as it sounds, though. Don't let yourself be too disturbed by Disturbia.

  • Run This Way

    You will probably just want to lay down when you see this giant air mattress, but keep your wits about you because it takes a lot of concentration and quick feet to work your way through this. Keep your head down and watch your footing!

  • Bust on Thru

    You'll have to be sure-footed and have your wits about you to make it through this obstacle, which resembles a long tire section and includes four inflatable doors that you have to bust your way through to make it to the end.

  • Jump Around

    "Jump up, jump up and get down" inside of this giant inflatable that looks kind of like a baseball glove. More than 70 feet of jumping excitement will keep you moving and having a great time as you make your way through the Insane Inflatable 5K course.
