Krispy Kreme Challenge Caloric Breakdown

This weekend 6,000 runners/walkers will attempt to inhale 72,000 Krispy Kreme glazed doughnuts....during a race!

To complete the KK Challenge, runners/walkers must trek from NCSU to the Raleigh store and production center (2 miles), eat a dozen glazed doughnuts (not hot), and then make the return trip (2 more miles), within a time limit.

So what is the caloric breakdown of this vomitous yet enticing event?

1 glazed doughnut = 200 calories
12 doughnuts = 2,400 calories
72,000 doughnuts = 14,400,000 calories

1 mile of running/walking ~ 100 calories
4 miles of running/walking ~ 400 calories

2,400 calories IN - 400 OUT = 2,000 gained

1 pound of fat = 3,500 calories


What does this mean for competitors and participants?

Well, first it must be noted, that the above calculations are not exact. We burn calories at different rates based on our age, gender, body type, etc. But, in general, it can be estimated that traveling 1 mile will burn about 100 calories, whether it be walking or running.

So based on these estimations, if a participant were to consume all 12 donuts, she/he could stand to gain about a half a pound, not taking into account what they consume or burn the rest of the day. For example, if this person typically burns 2000 calories a day, and she does not eat anything else that day, she will essentially break even for the day and not gain any weight. But I do NOT recommend this strategy (for the KK Challenge, to compensate for alcohol consumption, or as a means to lose weight or avoiding gaining weight.)

To play it safe, a participant could choose to only eat 2 doughnuts. This would assure that they were calorically even at the end of the event. And while this is one real life method for tackling weight loss ( by considering calories consumed and calories burned and striving for balance or a caloric deficit), what would be the fun in that in this circumstance? :)

So my realistic nutrition advice would be this:
If you're gonna do it, do it. But don't let this be a regular occurrence. If you allow yourself too many exceptions for overdoing it, it will add up. Every day there is a birthday, special occasion or reason to overeat or treat yourself. Don't deny yourself, but choose your treats wisely and carefully.

Sidenote:
If I were stranded on an island and I could eat all the yummy nutritious foods the island had to offer AND I could bring two foods from the modern world with me it would be KK glazed doughnuts and McDonald's fries (assuming they would taste like they were prepared fresh at their respective establishments.)

What one or two treats could you not live without???
