Do you want more excitement than summer's standard 5K? Find a group of mud-hungry friends or go it alone for this dog-friendly fun run. Encounter a series of mudpits, Slip 'n Slides, and haystacks along the sloppy obstacle course. Don't leave the kids at home–the Piglet Plunge offers children 12 and under a chance to revel in the messiness alongside you. Proceeds benefit Paradox Sports, a charity that provides sporting opportunities to the physically disabled. Sun 9 a.m.
