Very good post and spot on. There is most likely a lot of jealousy involved. I think she was doing better on social media than most of them, and also got substantially better sponsorship deals due to her larger reach. Girls in general are just overly competitive and often get upset, if someone beats them in a race or workout. Or if someone is more popular than them.
I've seen guys lose a race to their best friend/teammate, and go out for a drink/meal afterwards.
I've seen females lose a race to a teammate or close friend, and drop the friendship for literally no reason.
There is a reason why famous teams like Tinman Elite don't even have a women's division yet. Lots of possible drama, especially behind the scenes.
