When is the Palio / Should I see the July or August Palio?
There are two Palio races: July 2 and August 15. The races are identical so you can see one or the other. Only 10 of 17 contrade will compete in any given race. They are selected by lottery so different districts will compete in each race. Another difference is that the August race starts a bit later, normally around 7:30 p.m. rather than 7, because of the heat.
