Apparently, in her mind this was a Michael Jordan with the flu situation. She has pictures afterwards in a hospital bed getting an IV and bragging about how you have to do what you have to do.

Now all that said, I'm a little sympathetic, as apparently shitting yourself during marathons and the like is not uncommon, but this was some weird crossfit thing where you are indoors and constantly getting down on the floor for various reasons and using provided equipment, so anyone who came after her was wading through her poopies. I think you have to be capable of being very self-centered, at least temporarily, to be a truly elite competitive athlete, but somebody should have thought this one through better.
