The jockeys ride the horses bareback from the starting line, an area between two ropes. Nine horses, in an order only decided by lot immediately before the race starts, enter the space. The tenth, the rincorsa, waits outside. When the rincorsa finally enters the space between the ropes the starter (mossiere) activates a mechanism that instantly drops the canapo (the front rope). This process (the mossa) can take a very long time, as deals have usually been made between various contrade and jockeys that affect when the rincorsa moves - he may be waiting for a particular other horse to be well- or badly-placed, for example.
