I'm an avid cyclist and ride lots of miles per year. No computer. No electronics. No power meter. No GPS. No nothing.
I don't bother with "group rides" anymore because, well for starters I'm sick and tired of the "I'm Lance" crowd always biking off and riding like dicks - but they all have one thing in common - they're quite figuratively buried in electronic gadgets and spend 90% of their time on the ride staring down at a computer display and shouting out numbers at each other in some sort of ersatz dick-measuring contest to see who's is "putting out more watts!"
This obsession with electronics in sport is ruining sport. It's no longer sport. It's my computer versus your computer.
