Women who lose out to transgender rivals at Parkrun demand competitors born male are barred from female race
A campaign group is urging parkrun to prevent transgender women from registering in the female category, arguing that competitors born male may have physical advantages and that the policy is unfair to women and girls. The dispute matters because parkrun is a large nationwide community event, while prominent athletes and campaigners are also threatening legal action over its eligibility rules.
Reality Rules Runners UK is launching a mass sign-up campaign through participants’ parkrun profiles, and says it wants to demonstrate support for sex-based categories. Olympic swimmer Sharron Davies, yachtswoman Tracy Edwards and the Women’s Sport Union have reportedly given parkrun until next Friday to change its policy; former marathon runner Mara Yamauchi says transgender women hold 20 female local parkrun records, including two course records. The article says parkrun has more than 1,400 UK events and links the campaigners’ argument to a recent Supreme Court ruling on the legal meaning of sex.
- Campaigners want parkrun’s female category restricted to people born female.
- Leading athletes have threatened legal action over the policy.
- The dispute centres on fairness, records and sex-based eligibility.

parkrun is a free, weekly timed 5km event held in parks and other public spaces, with more than 1,400 locations across the UK. Participants can register in categories including male and female, and the rules for transgender women entering the female category have become contested.
Reality Rules Runners UK and other campaigners want parkrun to restrict that category to women they describe as biologically female. They say physical differences may affect competition and point to records held by transgender women; parkrun’s eligibility policy is the focus of the dispute.
The debate concerns how community sport should balance inclusion with sex-based competition. It also follows a Supreme Court ruling on the legal meaning of sex, which campaigners say is relevant to parkrun’s rules.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Supporters of sex-based eligibility rules argue that differences associated with male puberty can confer lasting physical advantages in running, making female categories less fair to women and girls who compete on equal terms. They say clear rules based on sex would protect meaningful female records and competition, and that parkrun should consider this principle consistently across its many events.
The case against
Those favouring parkrun’s inclusive policy argue that community runs should welcome transgender women in the category that reflects their gender, especially where participation is recreational rather than elite competition. They may question whether performance records alone show that the current rules cause significant unfairness, and argue that excluding transgender women risks denying them dignity and belonging without a proportionate benefit.
