By Blood, Sweat & Cheers

From fireman themes to a water park turned into an obstacle course ... From 5Ks to full blown marathons ... Mud runs just continue to get more and more popular.

Events with one or two locations across the nation exploded into every state. Established obstacle courses started going global. All over the country, a movement of people looking to break out of the ordinary routine broke into the extraordinary experience of getting down and dirty.

And a beer at the end of every race didn't hurt.

Check out the slideshow for a rundown of our (current) favorite mud runs in the obstacle course landscape.
