Choose between a 4K, a chip-timed four-miler, and a kids' 400-yard course at this patriotic run. (You're encouraged to proudly sport your stars-and-stripes attire.) Stick around after the races for a free old-fashioned crawfish boil, Pabst Blue Ribbon beer garden, and an all-American Slip'N Slide for all ages. Mon 8 a.m.
