parkrun Australia: 🧵

Today, two little girls achieved a very special 1-2 as the top two females to finish. I’ve never seen this before. It might be the first time ever. Two v impressive & fast little girls.👏

Sadly, their achievement was ruined by a male in middle age, who… …runs in the F category & finished 2nd. So the two girls were ‘only’ 1st & 3rd in the results, their special (historic?) achievement stolen from them by a man. This man also stole better finish positions from >90 females in total. He already holds the F age category record…

I see the ‘genital inspections’ excuse has been wheeled out by numerous Democrats in Congress, as it has been by many who defend males in the F category in the UK.

This term shows that the person using it:

a) is ill-informed;
b) has made no effort to learn the history… …of sex testing (see @coachblade @cathydevine56 @AlisonSydor & others);
c) is uninterested in sport & particularly fairness & why categories exist;
d) is unthinking;
e) is deliberately spreading fear;
f) is denying that everyone knows what sex they were at birth;…

Hi @Jimmigrant1, you posted this article as proof that being asked to register by sex would put trans people off parkrun. I’ve now had time to look at it. I am starting a new thread bc it needs to be seen widely. My conclusion is it is misleading…

bjsm.bmj.com/content/58/23/… …& biased gender ideology-promoting propaganda.

1. The BJSM is captured by extreme gender identity ideology. For example, it pushed this anti-reality nonsense, eviscerated here by @FondOfBeetles. Please also listen to the @sportsscipod episode which also eviscerated it….

This article about parkrun is extraordinary:🧵



1. The true meaning of “inclusion” is everyone is genuinely & fairly included. The Female category *is* the inclusion measure for females, because of males’ massive physical advantages. This seems to be… independent.co.uk/life-style/par…Image …entirely lost on PSH since parkrun’s version of inclusion is to let males run in the F category, thereby getting rid of the F category.

What parkrun is doing is not “inclusion” but validating the demands of men who say they are women, & excluding women & girls from things…

Thank you @maanvis81 for posting this interview w Petrillo. Please watch.👇My thoughts:

1. What elite female athlete wears massive dangly earrings which will get in the way of an optimal performance? The last time I saw this was on another male in the Female category, Austin.. …Killips. They can afford to unnecessarily risk impeding their own performance with such things bc they are male w male advantage. And of course it is a performance of ‘woman’ for them.

2. “I don’t hurt anyone”. This is an egregious lie. He has stolen a place in the…

I was on @PatrickChristys’ show last night. Full clip here from 22:35. 👇

Male runner Glen Frank constantly talked over & interrupted me - he’s a man! He also made host Patrick’s job almost impossible. A few key points I want to note: thread.

gbnews.com/shows/patrick-…
1. Glen said “I do agree with Mara that there’s no ruling yet to include transgender athletes”. I had not said anything on this. The “I agree w Mara” was made up. Glen’s claim is false - @WorldAquatics spent a year creating an Open category for trans athletes and had no takers.

Thread.

In addition to Glen Frank, another trans-identifying male, Farrah Herbert, ran in the Female category of the London Marathon. The only way this could be within UKA rules is if he entered before 31 March 2023, and was in full compliance with the previous, May 2021 UKA…

Latest on parkrun & censorship:

@CannonHparkrun now seem to be saying it was nothing to do with them, but parkrun HQ. 👇 I think these are the instructions the local team must have followed. 👇
Starts with “…the risk of various groups….attempting to influence or change our policies and procedures”.

God forbid that anyone might try to change parkrun’s sex discrimination!

Trans-identifying male Sian Longthorpe has given up his four female @parkrunUK records. Good! 👍👏 Males should not participate in the female category in any sports at any level because it is unfair. Males in parkrun are well catered for with THREE categories (male, another… …gender identity & prefer not to say) which do not cause unfairness for females.

Finally, the actual females who are the record-holders can now be recognised, instead of erased. The new outright female record-holder at Parke parkrun has never been recognised until now…

If you missed @Emmabarnett interviewing Semenya on @BBCWomansHour just now, please listen.

1. Emma in intro omitted most important words about the rules - “in the female category”. Semenya is free to compete in the male category.

2. Emma noted the “lack of understanding”… …on this issue. Yes, because journalists like yourself omit the key FACTS. Please see my request below. If you stated the facts clearly, people would understand better.

I missed this parkrun statement on gender from 20 July.👇



Perhaps the biggest problem in the gender & sport debate is the widespread failure (by accident or by design) by so many to recognise that the female category **IS** itself an inclusion measure…parkrun.com/blog/news/2023… Without the female category, females are EXCLUDED from sport bc of the massive advantages males have - explained by @FondOfBeetles at 0:48 into this short film.👇



The female inclusion measure caters for the biggest group (51%) who otherwise would….

Thread: here are 2 examples of the impact of males in the F category in UK distance running.

1. A female athlete had her club age group record taken from her by a male in 2022. In solidarity with, & support for her, a different female athlete has now taken it back. So female… athletes are quietly cooperating to get what males have stolen from them back into female hands.

2. Since UKA banned post-puberty males from the F category on 31 March, a male has broken a UK club female marathon record, presumably under the transitional arrangements. This is

My very last thread on this topic!

It turns out Sunday was not the first time Glenique Frank has run in the female category in the London Marathon.

He ran 4:45:21 in the Oct 2022 race as Glenique, in the female category, but was back to male for the NYC marathon in Nov 2022. In Oct 2021 he ran as Glenique but in the male category. Frank has apologised - good, thank you! 🙏

I want to highlight how this case illustrates the wider problems with male inclusion in the female category.

1. AFAICT, nobody much knew about him competing in the…

This article about male Glenique Frank who ran London Marathon in the female category is v interesting - please read. 👇Thanks to @georgeabtsports for flagging.

1. Frank seems to think his eligibility for the female category is about passports & “I ticked female because I… …see myself as female”. (Last night this said “felt female” but article seems to have been updated; unftly I did not keep screenshot.) In actual material reality, UK Athletics rules in force from May 2021 to 31 March 2023 determined eligibility. They required testosterone….

Today I tweeted about male Glenique Frank running in the female category in yesterday’s London Marathon.

In response @LibDems candidate @HarryMarstonLD tweeted this 👇to my MP, @munirawilson (also LD). This is a man telling a female MP who she’s allowed to follow/not follow. Image Harry called me a transphobe without a) defining it, b) saying what about my tweet he objected to, nor c) explaining why he (presumably) wants males in women’s sport.

He later deleted the tweet, after apparently critical replies, none of which I saw as I was out training. Image

This male ran in yesterday’s #LondonMarathon as Glenique Frank in the female category (Mass race) finishing in 6160th place out of 20123. So nearly 14,000 actual females suffered a worse finish position bc of him.

Last month, he ran in the Tokyo Marathon, as Glen Frank, also… in the F category, finishing 2829th out of 8609. So nearly 6000 females in worse finish position.

Last Nov, he ran the NYC Marathon as Glen Frank in the men’s category, finishing 14,096th out of 26,539.

Since 31 March, @WorldAthletics & @BritAthletics have banned….

Thread: ICYMI, please watch @BBCJohnBeattie’s interview with the UN’s @victor_madrigal about sport here👇, broadcast on @BBCScotland on 16 Dec.

To address his points: 1. “TWAW” and “so of course they are entitled to participate in women’s sports”.

Two barefaced lies. TW are MALE. Women are FEMALE. Changing sex is impossible, therefore TW are not & never will be women. Women’s sport is for those born FEMALE so NO, males are NOT entitled to…

Lots of interesting detail from Bridges here 👇.

1. The words ‘sister’ & ‘daughter’ are taken, by females. Bridges is male. Why have ITV allowed this? Image 2. Bridges blaming those who speak up against gender ideology for the Colorado attacks. No mention of alleged attacker being non-binary, nor that 2-3 females are killed per week in UK. Bridges dismisses widespread valid concerns by using “so-called” & quotation marks. Image

There are numerous points in this that need addressing. But perhaps the most important is this 👇.

I believe Bridges is referring to research by Joanna Harper, a trans-identifying male, which Bridges is part of. “I believe it will show that I haven’t got any unfair advantage”. The elephant in the room with Harper’s research is: how does Harper ensure 100% effort from the TW participants, who have an incentive to deliberately underperform in tests to ‘prove’ no advantage & thereby strengthen the case that competition against females by them is ‘fair’?

I was on @StephenNolan’s show on @bbc5live ystday at 23:20. After me, @PeterTatchell gave us all a lesson on #marathon physiology, inc saying TW are at a *disadvantage* compared to biological women bc the latter “have greater fatigue resistance & recover faster”. This is made-up, unscientific nonsense. Obvs I know bc I’ve done it ! 🤬Peter, why is the male (which is what TW are) WR over TWELVE minutes faster than the female WR? @bbc should not be allowing outright lies to go unchallenged on their programmes. @FondOfBeetles @Scienceofsport @TLexercise
