Have you been thinking to yourself, "What is the Insane Inflatable 5K all about?" Well, here’s a video showing some of our co-workers testing some of the many obstacles that runners will have face during the race this Saturday and Sunday at Millennium Park!

As you can see, these things are big, full of air, and look like a ton of fun! 

Don’t miss out on your chance to be a part of Grand Rapids' first-ever Insane Inflatable 5K this weekend! All of the Saturday race times are full, but there are still openings for Sunday's race. You don't want to miss out on the most fun race to hit Grand Rapids this summer!
