Well, speaking for myself, even though I know I do more, in terms of physical activity, than 99% of Americans, it makes me feel *bad* to hear about all the 5-10K a year people. There's nothing wrong with my self esteem, but truth is, even my DH wonders about this, and he is a very strong rider... but we just think we are wusses. I mean, if I do a 50-60 mile one day, I will not be doing that again the next day, unless I am on a tour. And people who routinely ride 100 miles every weekend? Well, if you are a racer, sure. If not, then you surely can't be doing anything else besides riding. So, even competition with myself doesn't work so much, because I often just set goals that are high. I am generally an extremely disciplined person, organized, etc., but even being around others who talk about this stuff makes me kind of annoyed.
