The crowds came out on a perfect Sunday morning, May 8, to experience the 2nd annual Insane Inflatable 5K in Missoula.

The University of Montana Golf Course was transformed into an outdoor "bounce house" for adults and their families. The runners - and those who were a little slower - were sent off in 15-minute intervals that took them around the course and over a great variety of inflated obstacles.

The popular event was brought to Western Montana by the Townsquare radio stations in Missoula and Hamilton and was sponsored by the Karl Tyler Auto Group.

Here's a sample of the fun.
