That is not protecting women’s sport. That is policing girls’ bodies.” 1133

Tranathon @tranathon.bsky.social · 26/03/2026Tranathon is a tiny campaigning group of UK trans people fighting for equal participation in sport. We have observed with dismay the increasingly hostile environment facing trans people who wish to engage in sporting pursuits with their peers at any age and at any level, 1312
Tranathon @tranathon.bsky.social · 26/03/2026Sex testing doesn't protect women - it targets and harasses women, replacing fairness with fear, science with stigma, and equity with exclusion. All women should feel safe and protected in women's sports. We stand together and will fight together. 1448
Tranathon @tranathon.bsky.social · 26/03/2026At Tranathon we know that as trans people we are the targets of this policy. But we also know that this is a racialised form of gender violence and that Global Majority women in particular will be targeted first, worst and always. 1413
Tranathon @tranathon.bsky.social · 26/03/2026It is deeply disappointing to see the IOC decide to sweep these well-documented problems aside in the pursuit of an ideological campaign to prevent a tiny group of women from ever participating in sport. 1423

Tranathon @tranathon.bsky.social · 26/03/2026Sex verification is not a novel concept in sport, with the IOC and IAAF having required chromosome testing in women's events from the 1950s to the 1990s.

Tranathon @tranathon.bsky.social · 26/03/2026Tranathon member Bridie says: “Running has been increasingly important to me over the last few years. It keeps me fit and well, and it helps my bone health, which can sometimes be an issue for trans women - especially if, like me, they were bullied in PE at school and did no sport until adulthood. 1464

Tranathon @tranathon.bsky.social · 31/03/2024Transphobes have tried to push trans people out of events like these, but we are here to show we belong and are welcome in these spaces, just as we should be welcome everywhere. We look forward to showing our results and sharing our experiences with you. 000
Tranathon @tranathon.bsky.social · 31/03/2024April is going to be a BIG month for Tranathon as we have members participating in both the Brighton Marathon (April 7) and the London Marathon (April 21). We are excited and proud to represent the trans community in these events. 100

Tranathon @tranathon.bsky.social · 29/11/2023They just think trans people are fake. Simple as that. The whole “advantage” idea is a distraction from that core belief which can be dropped in a heartbeat when they don’t think they need it anymore. 020
Tranathon @tranathon.bsky.social · 29/11/2023Here we see one of the more prominent anti-trans campaigners in the US stating the reality of the trans people in sports “debate” openly. It’s not about “advantage”, it’s about their belief that societal systems MUST treat trans people as their sex assigned at birth in all cases. 151

Tranathon @tranathon.bsky.social · 16/10/2023Parkruns are a wonderful opportunity for community and exercise that should be open and welcoming to all. These groups seek to change that. We are glad that Parkrun has stood firm on this matter, making clear on their website that they retaining their self-identification policy. 110
Tranathon @tranathon.bsky.social · 16/10/2023Transphobia in sports has largely centred around high-level professional sports and school sports (and those are also discriminatory). But they are now expanding to any public physical activity. This is an effort to expand anti-trans bigotry into wider aspects of public life. 110
Tranathon @tranathon.bsky.social · 16/10/2023Right here is a clear example of what we're trying to fight against. Anti-trans groups have recently made a push to target local parkruns (the free-to-enter, non-competitive, mixed-gender events) for basic trans inclusion. www.thepinknews.com/2023/10/02/p...thepinknews.comAnti-trans activists protest non-competitive Parkrun event over trans inclusionAnti-trans activists have staged a protest at Parkrun in Manchester over trans women being allowed to participate. 122
