Hermes makes an intresting point, and it's one I've thought about a bit. I really do not like cycling all that much. It hurts sometimes, and it makes me tired. Drivers scare me, and I have trouble with the nagging, largely irrational, fear of instant death on the grille of a pickup truck. The scenery around here isn't all that interesting, and much of the year it's really hot and humid. That said, while I'm not a big fan of riding, I really love having ridden. I enjoy how I feel after, I like the many health benefits, I like the amazed looks I get from people when I tell them about my rides, I like how it makes me look, and there are a dozen other things about it that I love. Sometimes when the weather is nice and I'm feeling good, riding is fun. But mostly it's a chore done for the benefits on the other side. And it beats by far every other form of exercise that can provide similar benefits.
