Thanks to so many regular parkrunners/volunteers across the UK who sent me their photos calling on ⁦⁦@parkrunUK⁩ to do better and stop unfair self ID! Sorry I couldn’t use them all. Please keep sharing and encouraging others to make their voices heard #savewomensparkrun

Email the person and say "you seem to be registered in the wrong category. Here are your options - register as M, register without sex. Please correct your registration within X days or let us know if this a mistake on our part. " Etc The normal thing to enforce TS and Cs

.@parkrunUK did exactly this to me but a bit more brutally

“Across all running events, males (aged 7 to 9) consistently outperformed females, with an average performance advantage of 4.9 %” This is why it is grossly unfair to school girls to only have mixed-sex sport options; setting them up to fail even before puberty

The first conclusion from the @void_if_removed review of the @BJSM_BMJ paper - debunking their claim that transwomen (biological males) have no advantage over female athletes The SEEN in Sport website has an abundance of peer reviewed research; showing male advantage increases from birth and is not removed by years of testosterone suppression

Another debunking of the @BJSM_BMJ claim that transwomen (biological males) have no advantage over females in sport Yes there’s overlap between elite women and untrained men (Graph 1) But compare elite women v elite men and the overlap virtually disappears (Graph 2)

London Marathon is in April. Every year since UKA banned males from the Female category, males have competed in it. The 2026 race, including the Mass race, is under EA’s licence and therefore males are still banned. So how many males will break the rules this year?

Timed and ranked results are important to the majority of the @parkrunUK community Women and girls are lawfully entitled to the same fairness in results as males enjoy. All it needs is a simple sex at birth registration policy and an expectation that people will be honest

There was a time when a women's Olympic gold medallist confessing he's really a man would have been front page news, @BBCNews @itvnews @Channel4News.

Great interview with @mara_yamauchi and @DerryBanShee bringing more facts on the unfairness of allowing males into grassroots sports and recreational activities

Is Bunce going to apologise to all the people he called “anonymous fools” who stated the truth that Khelif is male? 🤔

The @milanocortina26 Winter Olympics have begun Although the International Ski Federation protected the female category in Sept 2025, @SnowsportEng @SnowsportWales and @Snowsport_Scot still allow males to participate in all levels of women’s snowsport Details of the unfair policy and how to contact those in charge follows

Well this sign sparked A LOT of reaction at a grass roots race tonight So many of the general public and runners coming up and saying Absolutely Totally agree It’s madness And not just boxing, keep men out of all female sport #IstandWithAngelaCarini

Agree. I will never be elite and it matters to me. Training for a marathon is very hard. Training for London requires running regularly over winter often in the dark/ rain/ cold. It's deeply insulting to belittle women who dedicate their time & efforts just for wanting fairness.

There’s nothing intimidating about women wearing T-shirts expressing support for fairness in women’s sport. No individual is being targeted, named or singled out. No rules have been broken. No one is prevented from participating. Disagreeing with a policy - or expressing a lawful view - is not intimidation. Calling it “campaigning” doesn’t change that.

I’ve been involved with parkrun for over a decade now - both as a runner and a volunteer - so I speak with some authority when I say the “it’s just a fun run” argument really doesn’t stand up. I’m speaking in a personal capacity here, but the most common queries I deal with as a parkrun event director are about times not being recorded correctly against participants’ names. That can happen for all sorts of reasons - forgotten barcodes, finish-funnel duckers, scanning glitches, you name it. And much as I hate doing it, I’ve had to say ‘no’ to people who achieved amazing PBs but didn’t bring their barcode on the day 🫣 (Thems the rules.) All of this tells you something important: participants care about times. And about fairness. That’s true across the field - not just for the front-runners chasing records, but those nearer the back too. Shaving a few seconds off a time, moving up a finishing place, improving an age-grade - these are all tangible markers of progress. Regardless of age, ability and fitness levels. They’re what keep many people coming back week after week, year after year. Which is precisely why sex categories matter too. Because if we accept that times, placings and progress are meaningful - and parkrun’s entire results system is built on the assumption that they are - then it also matters that people are being compared within fair, meaningful categories. Calling parkrun a “fun run” doesn’t change that reality. The data matters. And fairness matters - to participants at every pace.

A reminder to @FAWales and your CEO - it's almost 300 days since the Supreme Court judgment and you STILL have a policy that allows men to play in the women's game. No one can possibly take your daft announcements of virtue seriously, when you fail women. 1/4

#SaveWomensSports great turnout in Oxford this morning supporting fairness for women ❤️
