1. I didn't suggest that you can pick out dopers at gyms by how they look. But if you know anything about bodybuilding, you can certainly identify people in a gym who are much more likely to be dopers than skinny mountain runners. And it's not merely because of how they look. It's also because they've chosen a sport in which doping is rampant, if not necessary for success at the highest levels. I've never heard of any similar doping culture among American mountain runners and ultramarathoners. In fact, I would expect them to be among the least likely dopers in sport. They're much more likely to be ascetic vegetarians who won't eat anything that isn't organic and won't take any drug that isn't absolutely necessary to treat an otherwise fatal case of bubonic plague.
2. I didn't say that doping was irrelevant to a thread about the NYT article. In fact, early in the thread, I said that it was weird to see doping mentioned in the article. The author stated, "Carpenter has never been publicly accused of doping; he said he has never taken performance-enhancing drugs and was happy to be tested any time." What is that doing in the article? Do nonrunners like the author (yes, he is a nonrunner) really see our sport as being so dirty that doping is an integral part of an article about a good runner? It would be like an article about a Catholic priest with a paragraph stating that he has never been publicly accused of child molestation. It seems to me that an appropriate response might be that the writer shouldn't have included such a paragraph. I don't think that it's an appropriate or enlightening response to make the trivial assertion that nobody is above suspicion of being a doper or a child molester.
