Tarka Michel Bernard L'Herpiniere, born 19 September 1981, is a British explorer, ultra endurance athlete, motivational speaker and filmmaker who holds several endurance records.
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 to include Mt Blanc, Aconcagua and Cho Oyu before developing an interest in the polar regions.
After several successful small scale expeditions to the Arctic, in 2004 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 L'Herpiniere attempted to summit Mt Everest without oxygen.
At the North Col (7,020 m) L'Herpiniere developed HACE and had to be evacuated.
In 2007 he became the first person to walk the entire length of the Great Wall of China.
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.
In 2009 he completed the longest crossing of the Southern Patagonian Ice Cap by a British team and is currently preparing for his next expedition to the ice cap in August 2010 to attempt the longest-ever unsupported crossing.
