If you really value your running club, why not help them set something else up?
You could offer to help the people who do all that posting to get it onto an email list or some other platform away from Facebook. A small indie website somewhere, even a blog.
I know this sounds like work, and you just want to enjoy your running club, but if it gets sticky, the people who are currently posting everything on FB will eventually realise there's value elsewhere and they'll keep it ticking over.
They have a website, which is actually quite good, but it's the social aspects - lift sharing to races, posting about races that people are going to, etc. that
the social media is actually useful for. Nobody is signing up to a forum in 2025 to do this sort of thing, and WhatsApp groups which seems to be the alternative are way too noisy for my liking.
