There was a piece in the Independent not so long ago where a woman talked about being kicked or swam over by men when they swam faster than men and there were loads of responses with similar stories. So there’s probably non-religious women who prefer single-sex swimming too (not to say I don’t respect the religious reasons).
Yep. I, and many other fast, female swimmers, would go to the female only sessions, to avoid the aggressive behaviour of men who can't cope with a woman out swimming them, over taking them, and who would do stuff like swimming down the middle of the lane with their rubbish, flailing strokes, meaning anyone trying to get past them got clobbered.
I also carried on fast lane swimming whilst very pregnant, and could still out swim most of the men if I went to a mixed session. However, the risks of a kick to the belly were very real. Another reason for the need for single sex sessions is that many women find swimming the only form of relief and exercise during pregnancy. I've been a several times a week swimmer for 30 years, all in public pools. Women just do not pose the same sort of physical risk as men in terms of getting badly kicked, hit or crashed into.
