Abstract: The present invention relates to the field of race circuits and provides a racing circuit layout comprising: an interconnection between track sections of the racing circuit layout, the interconnection comprising one or a combination of: at least one crossover; at least two link sections, and, at least one barrier or traffic control mechanism operably associated with the crossovers or the at least two link sections, wherein the at least one barrier or traffic control mechanism is adapted to selectively configure the interconnection so as to provide multiple notional track sections in which combinations thereof form a set of unique racing circuits traversing the track sections and the interconnection.
