What started as a dare between NC State students in 2004, grew to a record-breaking 8,000 students, community members and supporters participating in ninth annual race in Raleigh.
The event, which supports N.C. Children's Hospital, kicked off at 8:30 a.m.
Participants ran 2.5 miles to the downtown Raleigh Krispy Kreme store, ate a dozen doughnuts, and ran 2.5 miles back to the N.C. State Belltower in under an hour.
The challenge hopes to surpass $500,000 in donations this year. Last year's challenge was the most successful to date, raising $127,000 to bring total donations to $374,000 over eight years.
Krispy Kreme reportedly cranked out 96,000 doughnuts for Saturday's event.
