It's the final week to register for the Insane Inflatable 5K Fun Run-Walk at the Fairgrounds, coming Saturday May 21st.

The 2nd Annual run features 11 different, crazy inflatable obstacles, from the Crash Course to the Slingshot and Wave Runner! Some are as tall as three stories, others will bounce you feet in the air.

It's fun for the whole family, and donations will benefit the YMCA of the Greater Tri-Cities. It all kicks off at 8:30a.m. The Newstalk 870 wave goes off at 9:30am.

IF you're over 21, enjoy some post-race suds with the Traveler Beer Company! Check out all the fun, with Newstalk870, and help a great cause!
