Skiers Set Out to Cross North Pole

OSLO, Norway -- Two Norwegian adventurers set off Wednesday on what may be the world's worst ski trip, a four-month trek across the frozen Arctic Ocean from Russia to Canada.

Rune Gjeldnes and Torry Larsen, both 28, hope to be the first to make the 2,700-kilometer trek on foot with no outside assistance or resupply of any kind.

In the past decade, nine expeditions have tried and failed to set one of the last great polar records.

The two men, members of a Norwegian navy unit, were the first to ski the 3,000-kilometer length of Greenland without any outside help or supplies.

They set off from Arktichesky Cape in northern Russia, with Russian soldiers firing their Kalashnikov automatic rifles into the air in a farewell salute, according to an Internet home page set up to follow the expedition.

The men are pulling about 170 kilograms of food and other supplies on sleds.
