The fact that horses play an essential role for equestrian sports raises rather specific ethical concerns. Questions like what should be morally permissible to do to (non-consenting) nonhumans for the sake of human interests become urgent. Is it not an example of (animal) rights violation to force nonhumans taking part of sport? However, in this article I argue, from a radical egalitarian point of view, that it is possible to defend the existence of equestrian sports, but not unconditionally. I suggest that it is the masculinity norms in the sports culture that compromise the already complicated relationship between humans and animals, and therefore become an obstacle for the vision of equality between humans and nonhumans.
