It does matter because you're all complaining about a fun run, where the times are often invented. It's not a race. It's not accurate.
I would understand some of the comments on this thread if they were aimed at an actual race where the timing was accurate and carried out by paid staff. With actual races, there is enough money involved to investigate any allegations of misconduct with record holders. With actual races, there is a concept of winning against other people. With actual races, the results do matter because they can be used as qualifying times for other races.
You're all complaining about a nice social activity run by grassroots volunteers (unpaid) on behalf of a charity that aims to get everyone outside doing some exercise at their own pace.
If it wasn't for parkrun, I would never do any exercise ever. Like many women who aren't particularly sporty, the UK school system robbed me of my confidence to exercise and didn't give me any opportunities to improve. parkrun has helped me see that I can compete against myself, and it's OK to be shit at sport but still have a go. I'm allowed to bring my full self to parkrun. I don't wear makeup or heels or attempt to be some ideal woman I see in the media. I just turn up as an unairbrushed, lumpy me, in all of my natural averageness. And I don't feel judged.
It's not intended to be serious. It's intended to be social, inclusive and welcoming. A trans person faces all kinds of struggles Monday to Friday - just read the attitudes on this thread - parkrun gives them an opportunity to turn up on Saturday morning as the person they feel they are, and to just run, walk, jog or volunteer. No masking, no pretending, just being themselves.
That's not just a gift reserved for trans people either.
We get people who are seriously ill and are too slow to participate in any other kind of sporting activity. They're welcomed at parkrun and supported by the community to do the whole course at their own pace or, if they're not up to it, what part of the course they can manage that day.
We get wheelchair users who can face accessibility challenges elsewhere.
We get women running in hijabs who feel out of place elsewhere.
We get DV victims rebuilding their lives and making links to new communities under a new name.
It's for everyone. And a lot of the groups that fall into everyone are female.
Honestly, those of you coming after parkrun are not seeing the bigger picture of what parkrun does for women. It would be extremely harmful to take down this organisation in your witchhunt.
Go fight your debate in competitive sport. Don't target a charity enriching the lives of women - and everyone else.
