Running 10K races and marathons can get pretty boring, which is why mud runs and obstacle courses are growing in popularity.

And now, one mud run is taking things to a whole new level of excitement by going X-rated.

The first annual X-Rated Run will be held in Bunnell, Florida, in February and will feature such obstacles as the Dominatrix Dungeon and the Blue Balls Dash.

At the post-race party, you’ll see porn stars, beer stands, and a mud wrestling pit.

To be clear, there will be no sex or nudity on the run – which is a good thing because the physical challenges will require all the strength and stamina the runners have.
