I agree, swimming is the most boring sport around (sorry, swimmers). But it sounded like the OP was on a spin bike, as opposed to a trainer, where you might be using it for music. Just wondering. I see people bringing their phones into the gym, setting them on the floor by their bike in spin class, or on the bar, even. They are not using it for music, so I am apt to judge that they can't be without their phone for an hour! Of course, I do not automatically associate phone with music. If I use the trainer at home, I have my old Ipod hooked up with the Boze radio, or I watch TV.
