This is the list of current riders at the Spanish Riding School. They've just taken on a large intake of new eleves (see bottom of list). In addition to Hannah (the first female who began a few years back) look at all of the female names on the list of new eleves. >>50% female intake assuming I am guessing the gender correctly from the names!! This may well change the dynamics of things at the SRS, especially as these females mature into assistant riders and so on. At my workplace, it always changes the nature of university committees when there is good female representation, so this may be the same sort of thing.
