The Arctic 1000
“The party completed the route in ultralight style, using fragile and lightweight gear considered absurdly inadequate by mainstream outdoor industry manufacturers. They slept under tarps made with the lightest racing sailcloth materials available, carried backpacks that weighed only 24 ounces but carried 55-60 lbs (mostly food), and cooked over bush fires. They wore trail running shoes - and carried no extra footwear. They traveled at night, and slept during the day - minimizing the amount of insulating gear they had to carry. The weight of their trekking gear, not including food and water, was less than seven pounds per person.”
