Earlier this month thousands of people ran in a circle while people threw colored powder in the air. It was fun, but if you're looking for more of a challenge we dare you to take on the Black Widow Mud and Sun Run Aug. 6 at Horn Rapid's Motorsports Complex. The Black Widow is preparing five miles through dirt, sand and mud impeded by about a dozen obstacles such as walls, tires and hay bales. Trust us, you won't be able to get your stroller through this course! If you don't believe us, take a look at these photos.
