Back for its second filthy installment this year, the Dirty Dash challenges you to go against everything your mother told you by running and slopping about in a muddy mess of inflatable obstacles. The course is 5.5 miles of muddy madness, but you can cut out early on a 3.5-mile shortcut. Kids 2–12 can get dirty on their own for just five bucks at the one-mile Piglet Plunge. Event held on Saturday, September 22 at Soldier Hollow in Midway. thedirtydash.com
