Dk why we're rehashing this again but this argument isn't an all or nothing thing on either end. Yeah, she got passed on the bike so she needs to push more watts. But someone with better bike handling might be able to do a lot better pushing similar watts. If you can't see that you just don't understand triathlon or don't want to because it doesn't fit your Mary Cain bashing agenda.
My Tri experience has been similar enough. I did a super technical Olympic bike & averaged ~270 watts. There were probably 12 180 degree tight turnarounds & I lost a ton of time on every single one of them relative to everyone else that finished right in front of or behind me overall. My target Olympic pace would be more like 290-310 watts based on FTP alone & I rode a lot of the race in that range. My problem wasn't that 270 watts is my max for the difference. My problem was that I didn't have the skills to ride closer to my max. My effort with better bike skills would have resulted in a much better bike split without making any power gains.
Mary is probably in a similar boat as a newer cyclist. With her engine, she probably pushes enough watts indoors that she can make some big improvements without increasing her output. Some of ya'll want to just hate on her for whatever reason. I honestly don't get it. She's been through enough but some of ya'll won't back off. Triathlon is a little more nuanced than the way some of you want to analyze her results. Pure running is straightforward & easy for a lot of people on here to understanding. Cycling in triathlon, especially as a new triathlete without a cycling background, can't just be a 1:1 comparison. It doesn't work like that.
