Because it's more than a sport, it's a whole way of life, of thinking, of communicating with others... Of course there is the awesome sensations when you look at the road under your front wheel, and you think :"This is so cool, I'm going so fast, just with the power of my legs!". But it's also the freedom of going anywhere, travelling, meeting people and looking around you, at human speed, without polluting, without being noisy, and also staying healthy. I went for a long ride this week end and I was a bit disappointed because when I started struggling none of the cyclists I was riding with slew down to stay with me. I guess it's just that we don't pedal for the same reasons.
Man I could go on and on with that... It's one of my favorite conversation topic...
