I have no idea who she is. However, the tone of the article implies that she's quitting because she didn't do well enough and is taking the easy way out with a "less demanding career." The words from the coach don't help. I don't think it's the case. She can't keep doing this forever, and there's no real money in women's cycling, which she points out. And the coach is saying "Shut up, we don't need that kind of talk 'round here."
