A 4 mile, military-style obstacle race in Oroville, Northern California

The Lord's Gym Mud Run tests the endurance and mental toughness of beginners and experts alike. Crawl through mud pits, jump over walls, run across rivers, swing, climb and hang by your fingertips as you brave our grueling 4 mile course. Awesome fun for both individuals and teams. Plus, all proceeds go to charity!

Four events in one:

The Main Race is open to everyone ages 13 to 101. Teams from local businesses can choose to compete against each other in the legendary "baddest" Business Bell competition. The Kids Mud Run is a separate race open to ages 4-12. Spectators and families can celebrate all day with food, inflatables, competitions and more at the Mud Fest.
