Previous experience

Polar Expedition: He recently made history by completing the longest unsupported polar expedition of all time, alongside his best mate, Jonesy. In 100 years of polar exploration no-one had EVER walked from the edge of Antarctica to the South Pole and back without assistance. Many had tried, none had succeeded. After 89 gruelling days they made it back to the coast after having skied 2275km with everything they needed to survive in the harshest environment on Earth.

The Ditch: Four years earlier they Crossed the Ditch – paddling 3318km without assistance across the Tasman Sea for another world first. They braved 10 metre swells, howling winds, endured severe food and sleep deprivation and adverse winds and currents. They became the first kayakers to cross the Tasman Sea as well as becoming the longest transoceanic double kayak expedition. Staggering upon the shores of New Zealand, the adventurers were sunburnt, bearded, underweight, and physically and mentally wasted…but most of all happy to be alive.
