Participants had to run 2.5 miles from the N.C. State bell tower to the Krispy Kreme in downtown Raleigh. Then, they downed a dozen doughnuts before running the 2.5. miles back to the finish line - all in one hour.
Runners said they consume 2,400 calories without hesitation because it is all for a good cause. Each year, the race raises money for the N.C. Children's Hospital.
This year's opening ceremonies were highlighted by an 8-year-old boy named Nathan Proctor. Nathan presented a check to the N.C. Children's Hospital for over $100,000.
Nathan lives in Oxford and has been a patient at the hospital since 2006, when he was diagnosed with CIPD (chronic inflammatory demyelinating polyneuropathy).
When he started treatment, Nathan had no nerves in his arms and legs and was unable to walk or stand. Now Nathan can walk and run and even plays baseball on a team. He has even been without medication since 2011.
