SPLAT! Jr. Obstacle Course Mud Run

Calling all junior mudders! The annual Splat Jr. Obstacle Course Mud Run brings tons of muddy fun to the Gans Creek Recreation Area. Splat will have walls, pipes, tires, climbing, crawling, cheering, encouragement, and of course, SO MUCH MUD! Depending on age, participants will complete 1K (4-5 year olds), 2K (6-8 year olds) or 3K (8-15 year olds).

The Splat! course and obstacles are designed to be age-appropriate in difficulty and distance. There are 10 WAVES (start times) at this year’s event, each with a 125-participant cap. Waves 6-10 (8 to 15-year-olds) are great for families and groups with kids in more than one age group who want to participate together. Please note that this is a longer course for 8 year-olds than WAVES 3-5. Registration includes a Splat t-shirt, Splat finisher medal and Splat bag.
