Just that really.
I've been avidly following the athletics and have noticed that at least two countries where the competitors are, how can I say this tactfully,? Are of dubious gender. 
and guess what. They win the races. Every time.
How can women compete against this?
How is it fair?
I'm prepared to get my arse handed on a plate but I don't care.
I think this needs to be discussed.
God only knows how it feels from a competitor's point of view.
No matter how hard you train, the best woman can't hope to win against'men'
