I think the biggest example that you can take from Chrissie is that she was very consistent in her approach and the results followed from that.
I made two significant deviations in late 2012/2013 that, in retrospect (duh), were not smart.
The first was thinking that I needed to drastically change my approach to swimming after Kona 2012. Rather than taking the view that it was over-racing (Leadman 3 weeks prior & IMNYC 9 weeks prior) that took away my front end speed, I decided I *needed* to become a better swimmer. I ended up doing what Sutton, ironically, talks about seeing numerous times. Guys become 1min faster in the water and 10min slower on the bike+run. Having now shifted my focus back to the way I used to train, i really wish I had invested that time in running instead of swimming, since there is a pretty clear correlation between volume:speed with running that doesn't exist in swimming.
The second is that I had always been judicious about how many races - especially long races - I did, never doing more than 2 in a 365 day period. Then, for all kinds of reasons some of which were dumb and some of which weren't, I did 5 eight+ hour races in 10 months between 2012 and 2013.
Now, granted, this isn't really that germane to the topic at hand, but I think what is noteworthy about Chrissie is that she was very good at "keeping the faith." Of course, she also won basically every race she ever did, which makes it a lot easier to have faith. But with Kona '12 really being my only really bad race in the prior two+ years, I look back and wonder "what the heck was I thinking?"
To loop this back to the particular topic at hand, I think it's often a wise decision to not mess with success. So, if you have athletes who win races - especially female athletes, where there seems to be a bigger spread on the bike, whether by tactic or physiology or both - without an aero helmet, I think it isn't necessarily "dumb" that they race without an aero helmet. If they are getting slaughtered on the bike, then sure, they might want to think about it. But for some of them, they are posting the fastest bike splits in spite of this.
