Alone with beautiful nature but held back by a sled that can never weigh less than 40kg. The sled apparently gets weighed at the start and finish.

Early on the 200 athletes in the field are tightly bunched and unlike in 2017 the weather was spectacular this time. Ingeborg Kristine Lind leads the pack here.

The event can be done as an individual or in a team of two. The team pictured here is Tarald Kleppe Ovrebo and Erik Tjolsen of Team Brynje of Norway.

Amy Mir apparently does Expedition Amundsen as a warm up for a 30 day expedition along the Norwegian border - according to Kai-Otto Melau

Pictured here is adventurer, climber and polar explorer Alexsander Gamme who apparently did the race for fun.

Truly alone with nature and your own thoughts in a stunning environment.

This is very hard work, but the views are rewarding.

With the sun going down the mandatory rest period is coming to mind.

The advantage of a team is that there is always someone who has your back.

Kristian Horne ended up in 3rd place, but here he is during his mandatory 8 hour stop. Horne is an experienced Norseman triathlete, but is usually not the only Norseman in this event. Plus other triathletes have taken on this challenge.

The tent of Haavard Hansen who won the race in course record time.

As it got dark the temperatures dropped and the tents were a welcome sight.

Pitch dark

After the mandatory rest Haavard Hansen pushed on to the finish. His 21:40 winning time includes the 8 hour stop.

The Viersla checkpoint is around 70km and that means close to home.
