Four races (2006, 2007, 2008 and 2010) in the Red Bull Air Race World Championship have been held on a stretch of the Swan River called Perth Water, using Langley Park as a temporary air field. Several motorsport facilities exist in Perth including Perth Motorplex, catering to drag racing and speedway, and Wanneroo Raceway for circuit racing and drifting, which hosts a V8 Supercars round. Perth also has two thoroughbred racing facilities: Ascot, home of the Railway Stakes and Perth Cup; and Belmont Park.
