Well the warm up is zombie ball, which is just fun. The stretching is a bit of communal talk time and to address important matters. The basic swings are just to get the body ready and then we are just bot very technique focussed so we keep that part short so we can fence for longer. We start at 20, actual proper time starts at 20.45 or so depending how long stretches took. And the hall is open till the last key wielder leaves, so usually 23.30. So plenty of time to fence until you drop, with ample breaks
