I think it's a great "feel-good story". Woman works full time job as a nurse, trains on her off-hours. Finishes 2nd in the Boston Marathon. No sponsors. No agent. Self-coached (from what I can tell).
If anything, she is more of a "blue collar runner" than Des Linden is because of the above.
Can she capitalize on this? Sure. She's more relate-able to the average runner, I think, than a Shalane, a Des or a Hasay. Sponsors love this kind of story, but she needs to strike while the iron is still really hot. It's not a very big window at all and to be honest, she'll probably be gone from the public's eye in probably a week (if that).
That being said, I'm not sure I'd quit my day job. It's a great job, making a difference in peoples' lives and pays really, really well.
