MUD RUN9 a.m., Two Rivers Park. $25-$35.
There are foot races and then there's Mud Run
. Billed as “Little Rock's dirtiest 5K,” the annual race invites participants to “run, walk, skip, trot and even cavort through our 5Kish course.” This year, the route snakes through Two Rivers Park. Along the way, racers are faced with obsta-cles. Three years ago that meant tires, two years ago hay bales, last year a human shield. The culmination, of course, is a giant mud pit, which all are forced to muck through. Prizes go to the top three fastest finishers (for men and women), the cleanest, dirtiest, best costume (adult and child), best entrance while in the pit and for stick in the mud. Visit mudrun.org for more rules and registration details. Also, there's a photo gallery to give you an idea of past costumes. You won't be original in a toga, a ladybug costume, a Batman outfit, a fat suit or covered in green body paint.
