Womens' 800m running is being sacrificed at the altar of political correctness and the relative high media profile of transgenderism currently being popularised (if that is the word) by Caitlyn Jenner, etc..
Its also being supported by the typical type of nerdy misogynistic male that sits behind computer keyboards spewing out vitriol against half the population, which has more to do with their own track record than any biological imperative.
Surely all that is needed is that where a chromosomal difference from a biological woman gives a physical advantage in another sport, the athlete should run in the more difficult category opened up to them by that genetic differentiation. ie Semenay, Nyonsaba, etc should run with the men. Why do intersex or transgender athletes ALWAYS want to run in the easier category (with the women)?
Athletics needs to get this sorted out, or look forward to biological women competing in the Olympics becoming a relative rarity and to amputees with highly engineered limbs breaking world records in non-disability sport.
