This is how I feel.
Carrying on with poo running down your leg, where others can see, smell and (very likely) end up in physical contact with your poo...I can't make sense of what she was thinking.
I can't imagine the humiliation of very obviously and publicly soiling myself, let alone thinking "ah, I'm winning the event so I'll carry on" .
I'm not saying its acceptable to shame someone for soiling themselves btw, incontinence can happen, I just find it incomprehensible that she didn't immediately want to take herself out of the public situation and clean up in private.
And being filmed where pretty much the world can see it...not just people connected to the event but everyone.
