Since her hair is at the back of her head, it probably helps with the turbulent air coming off the back of the helment.
OTOH, Beryl Burton appears to have sported a short hair style in her riding career, and she certainly didn't hang around.
As someone who has never had long hair (and is unlikely to at my rate of balding), is there an influence of spare time on length of hair? I know I have had requests for dates turned down many-a-time by women citing "washing my hair" as an excuse, but does long hair take that much extra time and hassle to keep it in good condition that amateur or semi-amateur athletes previously haven't had the time/energy to do?
I'm certainly no athlete!
For years used to have long enough hair for a pony tail, then there was a CC Ecosse tour planned, 4 days on the road: I cut my hair very short and stopped dying it too, pure au naturel.
It did not make me any faster, but it certainly made things easier.
I left it that style ever since, great for the bike.
My impression is that quite a few young women do not embrace the feminist label, all the while taking for granted many of the things that earlier feminists had to fight for.
Did you know the young ones started to wear corsets again, to make them look slimmer?
When I said to my colleague that her ancestresses fought for the right not to wear corsets she was unaware.
