Hi Lauren, in vic if you want to warm up a horse you have to do it with the race prior. Also it needs to be nominated on a horses gear form that that horse warms up. If you were to decide to not warm up anymore you need to change a horses gear form. In North America horses will often warm up more than once but not here. They take warming up far more seriously there than here. In fact I'm finding less and less trainers warm horses up now.
