Yeah, that is crazy and stupid! There are lots of risks when running regardless of wearing headphones. Look at the 28 year old who keeled over at the NYC pre-race. They still don't know the cause. I run with my ipod at all times and it is not loud enough to completely cover the sounds of traffic. I am also more cautious knowing that I can't hear cars or people behind me so I look around more often. They really shouldn't instill this regulation unless they have a lot of cases to back it up. right now, they probably have more cases of issues with runners passing out or getting hurt in other ways.
