1968 London–Sydney Marathon

The original Marathon was the result of a lunch in late 1967, during a period of despondency in Britain caused by the devaluation of the pound.[1][2] Sir Max Aitken, proprietor of the Daily Express, and two of his editorial executives, Jocelyn Stevens and Tommy Sopwith, decided to create an event which their newspaper could sponsor, and which would serve to raise the country's spirits. Such an event would, it was felt, act as a showcase for British engineering and would boost export sales in the countries through which it passed.

The initial UK£10,000 winner's prize offered by the Daily Express was soon joined by a £3,000 runners-up award and two £2,000 prizes for the third-placed team and for the highest-placed Australians, all of which were underwritten by the Daily Telegraph newspaper and its proprietor Sir Frank Packer, who was eager to promote the Antipodean leg of the rally.[1]

An eight-man organising committee was established to create a suitably challenging but navigable route. Jack Sears, organising secretary and himself a former racing driver, plotted a 7,000-mile course covering eleven countries in as many days, and arranged that the P&O liner SS Chusan would ferry the first 72 cars and their crews on the nine-day voyage from India, before the final 2,900 miles across Australia:[3][4]

The remaining crews departed Bombay at 3 am on Thursday 5 December, arriving in Fremantle at 10 am on Friday 13 December before they restarted in Perth the following evening. Any repairs attempted on the car during the voyage would lead to the crew's exclusion.[6]
