The head represents a small surface area of the body and transfers a very small amount of heat. Studies have consistently shown that wearing a non ventilated helmet does not increase internal body temperature. This was simply a poor equipment choice that cost her the race.
Carfrae wore an aero helmet.
There is a difference between over-heating and the perceptionthat you are over-heating.
If someone thinks they are over-heating, they will likely slow up or adjust their power output. You can't assume that their power would have been the same.
Could she have gone 2-3 minutes faster? Absolutely. Would she have done that? No one knows.
I know what you are saying. Macca and Crowie both wore vented road helmets in the past. Macca never won Kona until he wore an aero helmet in 2007. In that year, Macca ran 2:42. Crowie finished 2 min behind him and wore a vented helmet. In 2008 Crowie won wearing a vented helmet. Same thing in 2009. 2010, Macca came totally decked out in all the aero gear he could get including aero helmet and won. Crowie wore vented that year. Next year Crowie shows up with the full "HOLY SHIV" set up...aero everything and sets the course record and actually won the race on the bike. Ralaert and Jacobs ran faster but could not close the gap.
Since Chrissie, all the women's races have been won on rides with aero helmets...Rinny + Cave.
Since 2000 I am pretty sure that the only guys to win Kona on a vented helmets were Crowie (2008, 2009) and Tim de Boom. Peter Reid, Stadler, Faris, Macca, Jacobs, Crowie (2011), Kienle all on aero helmets. Van Lierde wore a stubby helmet for Kona last year. Not sure what you count that in.
