Ross Edgley famously ran a marathon pulling a 1.4-tonne car and climbed a rope the height of Everest (8,848m), after living with Yamabushi warrior monks in Japan and partaking in Shamanic pain rituals with fire ants in the Amazon jungle. On his epic 1,780-mile journey around Great Britain, which lasted 157 days, Ross swam through giant jellyfish, arctic storms, 'haunted' whirlpools and polluted shipping lanes, going so hard, and so fast, his tongue fell apart.
