I'm expecting some catastrophic event to happen so she can't do the ironman.  I suppose the event could be something as simple as "Some asshole stole my bike so I can't do this now!".  She would then turn that in to a soap box of how "haters" just wanted to keep her down.    Now that I reread what I've written, I find the above scenario likely.  She gets to "save face" while bitching about "patriarchy shit lord oppressionists".
