Children and adults alike participated in the second annual Big Bro Muddy Challenge at the Johnson County Fairgrounds on Saturday.

Part of the course sent the participants through the shallow waters of a small pond on the grounds.

Participants crawled through a tunnel section.

Participants had to navigate through a pit of water and mud while climbing up and over logs.

The log pit was both fun and challenging for the participants.

Runners struggle and stumble through the muddy waters.

Another favorite area of the obstacle course was the huge slide.

Runners also had to jump up and over huge bales of hay on the the course.

The final stretch of the obstacle course took participants, like this family, through a huge pit of mud.

This family, dressed in luau attire complete with grass skirts, coconut bras, and vibrantly colored flower leis, climb over a pile of tires on their way to the finish line.
