Twelve donuts and four fun miles make for one sticky sweet race! North Carolina State University organizes the
Krispy Kreme Challenge to benefit the NC Children's Hospital, and last year they raised $100,000. "Challengers" must finish the race in under an hour and eat a dozen donuts at mile two and, er, keep them down. "Casual Runners" can eat as many or as few Krispy Kremes as they want.
