The event plays host to a variety of racing categories, including production cars, sports cars, open-wheel racing cars and historic cars, which take part in sprint races, endurance races and regularity sessions. Around 300 vehicles are entered for the event each year, with crowds of up to and over 10,000 people attending the event. Car clubs also attend the event, displaying their cars within the confines of the circuit and performing parade laps.
