Oh I can run quite fast when I really want to. I've been first in age group a couple of times, on the harder trail courses granted, but still it's amazing the difference 1 day can make when you're changing age group. And yes it's nice to be able to say you were 1st in something, but I didn't get any prizes for it, because there are no prizes. And if I remember rightly the week after when I didn't get 1st in age group, I was actually quicker.
So you take a pride in your performance and enjoy the element of competition, however ‘relaxed’ it is re accuracy. There are other female runners who really strive to be the fastest and this element of competition is clearly popular, however informal.
It has a certain degree of inaccuracy built in but that is the same for everyone and their expectations can be set. Pretending that you have sex based categories for fairness when you don’t is deception.
Do you really think it is ok to take this sense of achievement away from women by allowing a male to set a record that unachievable for women? Who benefits from this? Men who wouldn’t have any noteable achievements in the mens list get to set records if listed as a woman. Women miss out.
