I wholeheartedly agree! Show me some science backing up this crazy belief that running with headphones is more dangerous than sitting on a sofa watching TV while eating a bag of chips. I always hear this belief but I never see any real hard facts. This is like being afraid of sharks when you are more likely to die slipping in your bathtub.
The fact that phones and music are banned in many marathons and branded Ironman events agravates me. Why can someone have a wrist computer and a bike computer but not a pocket computer? Why do they not want me to be able to communicate? I think a phone is nearly essential for safety's sake when you are out running or biking.
I am a triathlete. I run with my iPhone 5. The one with the size advantage of being small. It can last a 5 hour marathon. It lasts me for 6 hour bike rides. Sadly with IOS 9, in normal mode it will not last for an ironman, it can do a half, if you are fast enough, with gps and music. Put it in a plastic bag to protect it from sweat. Use bluetooth headphones that won't fall out your ears. Pay attention to your surroundings like a defensive driver. I like listening to music while I am running and biking just like people like to listen to music while they are in their car. I use my eyes and other senses to compensate for what my ears are missing. When I feel I need more situational awareness, I reduce the volume or take my headphones off.
Better yet, just outlaw music altogether. And the meek shall inherit the earth...
