Where is the Craziest 5K Held?

With the popularity of 5Ks growing every year, race directors have begun looking for ways to entice new runners. Enter the crazy-themed 5K.

From races completed entirely in the nudeto mud-filled pits and Krispy Kreme donuts, the possibilities for some unusual 5K fun are bountiful. Few races compare, however, with the Biscuitville Bowl's 7 Campus Scramble in Greensboro, North Carolina.

Runners of this crazy 5K choose to scramble through four biscuit-themed obstacles. Tires filled with wet grits, flour showers, a buttermilk slip-and-slide and a jelly belly crawl make this race one for the "crazy" record books.
