Spencer Matthews prepares to take on 30 marathons in 30 days across the Jordanian desert. As part of his training, Matthews ran with members of charities benefiting from Global's Make Some Noise campaign during a marathon run in London. If successful, the feat will earn him the Guinness World Record for the most consecutive marathons run on sand.
