Found in a Southampton scrapyard rescued by the MGB Register in 2015.

UMD 534F was driven by Jean Denton who was well-known for her rallying exploits. It was prepared for motorsport by Tom Boyce who would also serve as navigator on the rally. To prepare it for the rigours of the rally, the B underwent significant preparation work, including double welded seams, uprated headlamps and a double fuel tank that filled the boot. The passenger seat was replaced by a bed, which could be converted back into a seat for use during the day, while a selection of spares stowed beneath it.
The Marathon was promoted as 10,000 miles in 10 days. Starting in London and travelling through Europe and Asia to Bombay in India to then travel by boat to Freemantle near Perth Australia then on to finish in Sydney
The Denton/Boyce team finished the rally in 42nd place and was the only sportscar to complete the event.
The car has been in storage since the 1980s. The MGB Register have restored the car to its period works condition, with support from British Motor Heritage, Moss Europe, Abingdon Car Restorations and other trade partners. The restored car was launched at the Practical Classics Restoration Show in 2018, the 50th anniversary year of the event. It is owned by the MG Car Club and attends many shows around the UK
