RALEIGH, N.C. -- It's a challenge, all right.
In a charity race Saturday, more than 5,000 runners ran two miles to a downtown Raleigh Krispy Kreme shop, ate a dozen glazed doughnuts each and returned to North Carolina State University in less than an hour.
That's 2,400 calories and 144 grams of fat consumed while burning about 400 calories during the run.
The student-run Krispy Kreme Challenge raised about $35,000 for the North Carolina Children's Hospital.
The event began on a dare among college friends in 2004. Then-freshman Ben Gaddy won the first race by beating nine guys in about a half-hour.
His reward? A terrible stomachache.
