Even the Kardashians like to get down and dirty every once and a while!

Both Kim and Khloe Kardashian participated in a Mud Run in California on Saturday, going undercover in matching pink skull bandanas for the event.

The two chronicled their messy adventures on Instagram, sharing the photo of them above and another of them sliding into a pool of very muddy water.

"We Mud Run This Town," Kim captioned one of the photos, referencing fiance Kanye West's song "Run This Town."

We have a feeling this little day trip will end up on the next season of "Keeping Up with the Kardashians."

According to the event's website, the Mud Run is designed to test "toughness, strength, stamina, fitness, and mental determination." Wonder how they did!
