Kim and Khloe Kardashian don't strike us as the type to cover themselves in mud unless it's part of some luxury spa treatment, but the famous siblings have surprised us by taking part in the Mud Factor race on Sunday.
The Keeping Up with the Kardashians stars participated in the 5k mud run and shared photos from the event to prove they aren't afraid to tackle some mud.
Kim posted a photo of her and younger sister Khloe disguised in bandanas, presumably before the run while their make-up was still perfect, along with the caption, "Keeks & Kokes #MudRun (sic)."
Another Instagram post by Khloe shows the sisters sliding down a giant inflatable slide into a pool of muddy water.
According to the event's website, Mud Factor is a "seriously fun, 5k obstacle run", which involves 20 tough obstacles.
