Though she maintained multiple excuses for not coming close to competing with the best women (low mileage, low long run, three races the week before), she ran very well, especially considering that she went out in 1:15 and that this is a tough course. If she went all in on her training at a fast course, she would surely stand a good chance at breaking 2:30 in the next couple years.
I agree with this, although I think it would be more like 2:32. But even if it was 2:28. What would that net her? She would be about the 8th best American in the Marathon. Whereas she is the World's best in the Olympic Distance Tri right now. She should focus on that for the years she has left and also try to repeat at the Olympics. There is a LOT of Wheaties money available for even defending that kind of title.
