This is what Rune Gjeldnes packs in his expedition sleigh
Team Bergans member Rune Gjeldnes is a really tough guy and a real Polar hero. He has completed several extreme trips and expeditions, including the “Arctic Ocean” (over the ice from Siberia to Canada without supplies delivered along the route) and “The Longest March” (the world’s longest ski trek). Her are some of Rune's tips for what equipment to choose for an extreme adventure.
If you go on a trip that lasts for more than one week and the terrain is not too steep and hilly, it’s useful to take a sleigh with you in order to relieve your backpack and your body. There are many sleigh models in terms of both size and reliability. You should choose one which is suitable for the terrain you are going to be crossing. I always use an elastic rope on my sleigh to give me greater freedom of movement. This is particularly important in hilly terrain or terrain covered in vegetation. I also use a backpack together with the sleigh and can then vary the weight in the sleigh and the backpack as necessary. My favorite backpacks have been Trollhetta and Helium from Bergans.
This is what I have on my sleigh:
Cooking equipment (2 Primus stoves, 2 cooking pans, plate/cup, spoon)
Communications equipment (always one set accessible in the backpack)
Navigation equipment: map, compass and GPS
Repair kit (multi-tool, tape, Araldite, steel wire, hacksaw, hand drill, sail-making equipment, etc.)
Provisions (800 to 1,000 g per day)
First aid equipment
Toilet paper (2 meters per day)
Tent brush (to brush the frost off the tent walls, groundsheet and possibly underwear)
“Fun bag” (diary, iPod, lucky charms, pictures, toothbrush, books, etc.)
5 liter jerry cans (perhaps one in the backpack)
2 x 1 liter gasoline bottles
