Suffering weeks of frozen spray and icebergs, battling force 8 gale winds, hypothermia, and storms through some of the most treacherous stretches of water in the world, Grylls and his team were just barely able to finish the journey from Nova Scotia to Labrador, Greenland, Iceland and finally down to Scotland.

Paramotoring over Angel Falls - In 2005, Grylls led the first team ever to attempt to paramotor over the remote jungle plateau of the Angel Falls in Venezuela, the world’s highest waterfall. The team was attempting to reach the highest, most remote tepuis.

This was in aid of The Duke of Edinburgh’s Award and The Prince’s Trust.

Paramotoring over the Himalayas  - In 2007, Grylls broke a new world record by flying a Parajet over the Himalayas, higher than Mount Everest. Grylls took off from 4,400 metres (14,500 ft), 8 miles south of the mountain, eventually going on to look down on the summit and coping with temperatures of -60°C. The feat was filmed for Discovery Channel worldwide as well as Channel 4 in the UK.

Travelling at speeds up to 50 km/h (30 mph), a ski caught on the ice, launching him in the air and breaking his shoulder when he came down.

Longest indoor freefallGrylls, along with the double amputee Al Hodgson and the Scotsman Freddy MacDonald, set a Guinness world record in 2008 for the longest continuous indoor freefall.

The attempt was in support of the charity Global Angels.
