The above linked article is about a race that requires you to eat a dozen donuts along the 5K course. The title says miles, but it becomes clear in the article that it meant 5K. It originally took place in 2004 as a fundraiser in Raleigh, North Carolina. It has been put on pause, it seems, for now.
The article says that you can try it on your own. Running a 5K with a box of donuts or a stomach full of sugary, fatty donuts does not sound like a great idea to me, but to some, it might.
