There's basically no running involved. The only movement is getting from the perimeter to the center of the circle and then putting the clothes on and eating. Plus if you have a decent number of people playing the most any kid is likely to eat is a single bar. The kids are usually pretty fast to strip down due to wanting to get back into the circle and the other kid practically stripping them for a shot at the chocolate. No one I played with seemed to mind using the same fork, but if you're concerned or they are you could give each kid their own fork that they take in with them.
