If Trek wants to make this work as advertising I don't see how it could possibly work as it is. We don't read the blogs because we already know women like this.
What might work would be a lead-in advertisement. One page, a studio shot of a woman and her bike. A short paragraph about the woman written to target the audience for a particular type of magazine. Then something along the lines of "read about other women who ride at Trek.com" Advertising and outreach.
In my utopia, it would be nice to have a diversified outreach program. many of the comments here reflect a lack of diversity in some cycling communities and I'd like to see something done to change that. Trek's business is to sell bikes yes, but maybe they would find a wider market and sell more bikes? I don't know.

Imagine.
