Edward Michael "Bear" Grylls

In 2000, Grylls, led the first team to circumnavigate the UK on a personal watercraft or jet ski, taking about 30 days, to raise money for the Royal National Lifeboat Institution (RNLI). He also rowed naked for 22 miles in a homemade bathtub along the Thames to raise funds for a friend who lost his legs in a climbing accident.
• Crossing the North Atlantic
Three years later, he led a team of five, including his childhood friend, SAS colleague, and Mount Everest climbing partner Mick Crosthwaite, on the first unassisted crossing of the north Atlantic Arctic Ocean, in an open rigid inflatable boat. Suffering weeks of frozen spray and icebergs, battling force 8 gale winds, hypothermia, and storms in an eleven-metre-long boat through some of the most treacherous stretches of water in the world including the Labrador Sea, the Denmark Strait, and the stretch made famous by The Perfect Storm, Grylls and his team were just barely able to finish the journey from Halifax, Nova Scotia to John o' Groats, Scotland.
