I've trained since Walkmans first came out with a personal stereo. I won't race with one.
All I can say is wait til its you in the ambulance that can't evac, because they can't get around the IPOD wearer....
Wait til you're tripped up by someone who wont turn down their headset as they approach the finish line, not hearing instructions, or is more consumed with turning on their headset than the fact the race has started......
I work about 60 events a year..... it happens often.
and there are more novices wearing headsets than seasoned participants....the very people most at risk (How many people with a race number on their back have you spotted with an IPOD?)
So you'd be willing to sign a waiver that says...I revoke my right to sue any and all parties and assume ALL LAIBILITIES (that means they sue you directly for everything, and you'll cover the races legal costs too) for ALL damages your participating with headphones may cause?
AND FOR THE "expletive deleteds" among you that argue its the same as being deaf.....deaf people learn how to be aware of their surrondings......your very arguement says...."my IPOD helps me escape my surroundings....." amazingly people who would never sing Karaoke drunk, sing out loud wearing headsets
NOT ALLOWING headsets is a courtesy to all other participants, volunteers and emergency personal at the event
I bet you don't hold the door open for the person behind you, don't replace the roll of t.p. you emptied when you leave the bathroom, chew with your mouth open and don't cover your mouth when you sneeze and cough either do you?
