Australia's largest motor race ever, the 24 Hours of LeMons, with 100 cars and 600 drivers, will get under way on October 28 at the Wakefield Park racetrack in NSW.

No, that's not a typo. This is not the 24 Hours of Le Mans held each June near the 16th-century town where million-dollar racers from Porsche, Ferrari, Audi and Bentley fight for supremacy at up to 400km/h.

No, this is the 24 Hours of LeMons where $999 rejects from Mazda, Honda, Suzuki and Leyland will race very slowly near the 19th-century town of Goulburn.

Speaking from his office in Emeryville, California, LeMons founder Jay Lamm says he came up with the idea after "way too much beer and Chinese food". From one race in 2006, the schedule now includes 19 races and the three Concours d'LeMons across the US and the first international LeMons, at Wakefield Park.
