Reading Baron Pierre de Coubertin - Routledge Online Studies

But there is another reason, a practical one. Would separate
events be held for women, or would meets be held all together,
without distinction as to sex, regardless of whether the
competition is among individuals or teams?
The second of these approaches would be logical, since the
dogma of the equality of the sexes tends to expand. Yet this
assumes the existence of co-ed clubs. There are hardly any such
clubs now, with the exception of tennis and swimming. Even with
co-ed clubs, ninety-five times out of a hundred, elimination rounds
favour the men.
