River Rat Obstacle 5K

The River Rat Obstacle 5K & 1 Mile Fun Run is a fundraising event hosted by the Lexington Cross Country team in Lexington, Missouri, held on the Battle of Lexington Cross Country Course at Lexington High School. The 5K obstacle course features two loops with challenges such as hay bale hurdles, a car tire maze, an inflatable obstacle course, and a slip 'n slide finish. The 1-mile fun run includes hay bale hurdles and the slip 'n slide finish.

The mostly grassy and dirt trail course is relatively flat with minor hills and may become muddy if it rains. All obstacles are optional, and participants receive a race shirt. This is a fun run with no official timing or awards. Visit the organization's website for the most recent information.
