How's this for irony? A 58-year-old man who was competing in a North Carolina charity race that involved eating donuts at various times during the run, collapsed and died after experiencing chest pains.

According to People Magazine online, the race was being staged by a local Krispy Kreme store, as an event to raise money for various charities:

"Unfortunately we have some sad news to share," the Krispy Kreme Challenge organizers in Raleigh wrote on Twitter. "We regretfully confirm that a participant of today's Krispy Kreme Challenge has died."

The race participant "stepped out of the race within the first mile and reported having chest pains."

The man was rushed to a nearby hospital, but was pronounced dead. In no way, say race organizers, was the donut shop responsible, as runners are required to fill out paperwork and sign releases indicating they are aware of the physical exertions, and are capable of competing in the event.

According to People:

" The motto for the race is "2400 calories, 12 doughnuts, 5 miles, 1 hour."

Not all participants in the race must consume the doughnuts, only those who register as "Challengers." Those opting to complete the doughnut portion of the event run 2.5 miles before stopping at a specified Krispy Kreme location, where they must eat the dozen, glazed sweets before completing the final miles.
