Well, I don't preach to people who don't exercise at my level, and I try to keep most of it to myself, my DH, or our close friends who we ride and do other sports with. It's just when others ask me what I did over the weekend, etc, I try to be careful about saying how far I rode, etc, or go too much into it, and focus on the telling about the scenery or other aspects of where I went. I do plenty of other stuff, and another big part of my life is going out to restaurants and cooking. I eat healthy, but I'm no ascetic.
I may have validated their perceptions, but my closest friends who don't live this lifestyle just sort of accept it. I try to not make it an issue, but it has changed my social life. I've stopped doing activities at my synagogue, as it seems like all the people I know there are, well, not aging well, to put it nicely. I don't want to go to classes, lectures, or social activities on Sundays; I want to be on my bike or skis.
