Yes and there are dozens who seem pretty happy. Elle Purrier, Heather MacLean, Sinclaire Johnson, Emma Coburn and her squad, Jenny Simpson, the entire British professional contingent (Laura Muir has time to become a veterinarian despite the suffering involved with being a woman in running), pretty much every 800 runner seems to be outwardly doing well.
Maybe there's a problem here with large Nike professional teams based in the PNW? Kara's incident seems pretty identifiably centered on one bad relationship with a pretty bad dude. For others like Freshman there's just no way to separate malcontents and people struggling personally from the greater sport of "running." It's impossible and can never be done but there will always be those claiming it's a problem with "running" and not something wrong with their life making them unhappy. This exists in every area of life and I think part of being an adult is taking every broad complaint about society as probably true to an extent but usually not worth tipping the boat for.
It's fine for individuals to point out issues they see in a sport but it seems to take the air out of the room for the incredible world of US women's running going on right now. Ritz's team is tearing it up, everyone who recently left Bowerman seems to be running well, the 800 is stronger and more exciting than ever, there are multiple sub 4 women running at the same time for the US, Emily Sisson and Keira D'amato (what a f'n story!) are rewriting the history books in the marathon while Sarah Hall has an entire career after age 30 while raising an incredible unique family. Women are thriving in running like never before, do we have to give 80% of the conversation to the abusers?
