Don't get me wrong I understand what you're saying, I just don't agree with it. I don't think playing the older and wiser card is justification for claiming your goal is the more worthy/important/correct goal. And this has nothing to do with being offended or taking it personal because I'm trying to defend racing or that training to race is a loftier goal than pedaling around a bit on occasion.
Personally I don't race to compete against others, I do it to compete against myself. I couldn't care less what position I finish in or how fast (or slow) everyone else has done. Perfect example - at the Boulder Peak Olympic distance tri, every year a handful of people stuff them self into the canyon wall doing 35mph on the bike, I slow down through those tight corners because 20 seconds onto my race time is not worth risking not being able to ride tomorrow. I ride bikes because I love it, I ride every chance I get when it's dry. When I sign up for a race though that gives me the extra kick in the ass to get up early and get a trainer ride in before work, to go a little harder on the climbs, and to clean up my eating to get in better shape. The better shape I'm in, the longer I can ride. The longer I can ride the more fun I have doing it.
You're holier than thou comments fall right in line with a pet peeve of mine that I saw all the time in the Ironman world. People constantly saying things like "You ran a 10K? That's cute, my morning run was longer than that" and "Oh you did a marathon, did you do a 2.4 mile swim and a 112 mile bike ride as a warm up before it?" People love to act like their priority, their goal, their opinion, is the correct one and the measuring stick that all others are compared against, and that's bullshit.
