@Ihaventgottimeforthis I think why I feel so strongly is because it's not a neutral act in the wider context of women's sports and the issues surrounding that. With 2 daughters who are just reaching a competitive phase, who train hard in several sports and really find it useful to get a sense of how they're doing by looking at rankings etc, I don't want that obfuscated and I don't want there to be any lack of clarity in any sport.
There is an issue that is bigger than park run here. If they're saying that for some sporting events you can choose which category you go in but others you can't...it's just a constant push and erosion fo.boundsries. it becomes something they can say, "we've been doing this at parkrun and it's all fine" about and use that to also do it at the best thing or level. And why, if you are a TW, would you want this category change so much that you shout about it but be fine about sex categories in other sports and races. You won't be, you will also find that difficult/offensive and that will become the new battleground.
It is easier, fairer, more accurate and completely possible to say, "dress how you want, be called what you like, run however slowly or fast you please, but only register in your biological sex category" throughout sporting events at any level.
