L'Herpiniere spent his early years climbing, skiing, skydiving, paragliding and BASE jumping before turning his hand to large-scale expeditions. Initially, these were mountaineering expeditions including Mont Blanc, Aconcagua, and Cho Oyu before developing an interest in the polar regions. In 2004, after several successful small scale expeditions to the Arctic, he attempted to become the youngest person ever to reach the North and South Poles, unaided and in succession, but due to sponsorship withdrawal, the project could not be completed.

In 2006, he attempted to summit Mount Everest without oxygen. At the North Col (7,020 m) L'Herpiniere developed HACE and had to be evacuated. In 2007, he, along with his now wife, became the first person to walk the entire length of the Great Wall of China.^[1]

In 2008, L'Herpiniere cycled over 8,000 km through Africa on a 30-year-old bicycle with no brakes or gears to promote the charity Re-Cycle.^{[citation needed]} In 2009, he completed the longest crossing of the Southern Patagonian Ice Cap by a British team.^{[citation needed]}

In 2014, L'Herpiniere, along with Ben Saunders, replicated Captain Robert Falcon Scott's 1,795 mile trek across Antarctica from Scott's cabin on the coast, to the South Pole, and back.^[2]
