If she makes it to the start line, it will be interesting to see how she goes about the race.
Of course, if this is a legit BQ attempt, she'll need to go through the first half in about 1:45-1:50. If she tries to do that, I can see her bonking spectacularly and it could be a DNF or 5 hour+ sh*tshow.
If she's more realistic, and meets herself where she's currently at fitness and ability wise, she's got a much better chance of maybe running a steady 4:20ish (which would be a big but realistic improvement and probably close to what she should have been aiming for all along).
