The London–Sydney Marathon was a car rally from the United Kingdom to Australia. It was first run in 1968, a second event by the same organizers was run in 1977 and a third in 1993 to commemorate the 25th anniversary of the original. Three further rallies have subsequently been contested in 2000, 2004 and 2014.
