Registration is open for the Krispy Kreme Challenge, a student-founded event that raised $20,000 for the North Carolina Children’s Hospital last school year. Since opening registration earlier this week, Jordan Pung, a junior in biomedical engineering and co-chair for the event, said organizers have gotten a strong response. Registration is $10 for observers and $16 for challengers and casual participants. Pung said many people choose to be observers if they want to support the group but cannot come to the race. Racers will get to use technology new to the KKC, Pung said. “We’re putting in a chip timing system for challengers so they’ll wear a chip on their shoes that will more accurately record their time and make sure everything gets sorted out correctly,” he said. “It’s all provided in the registration costs.”More than 3,000 people attended last year’s event. To complete the Krispy Kreme Challenge, runners must run two miles from the Bell Tower to a Krispy Kreme on Peace Street, eat a dozen doughnuts, and run the two miles back.
