The three main temporary venue hubs are The Garden of Unearthly Delights, Gluttony and the Royal Croquet Club, and other temporary and permanent venues hosting Fringe events are scattered across the city, suburbs and region. In a period in Adelaide's calendar referred to by locals as "Mad March", other events running concurrently are the Adelaide Festival of Arts, another major arts festival starting a week after the Fringe, which includes Adelaide Writers' Week and the four-day world music festival WOMADelaide, and also the Adelaide 500 street circuit motor racing event, with accompanying evening music concerts.
