At the risk of offending swimmers, I find the sport mind numbingly boring. I’d rather be zooming around on my bike, running over hill and dale, than spending hours staring at a black line in the bottom of the pool. Sorry, but that’s how I feel. As do many triathletes. That’s why we aren’t very popular with some swim clubs, as well as the fact we can only do one stroke.
My sanity was saved by the creation of a very good underwater MP3 player. The Swim MP3 actually works. You wear it on your goggles and put its two speakers against your temples, not in your ears. Yes, you heard me right. For some reason anatomists would understand, the sound comes through crystal clear when you are under water even though you aren’t using your ears.
