Irvine Lake Mud Run

Get down and dirty at this wet and muddy 5k in Orange County. With multiple runs each year, including a summertime dirty dodgeball tournament, you can expect timed and non-timed races over dirt trails, hills and mud pits—lots and lots of mud. The organizers will provide plenty of showers, so you only have to worry about bringing a clean change of clothes. Both races kick off at Oak Canyon Park (5305 Santiago Canyon Rd).
