Strand was at a record pace until he had to stop after 21 hours. At that time, he had covered 427 kilometers. The record held by Hans Mäenpää is 472 kilometers.

Strand began to feel fatigued after 16 hours of skiing. After 21 hours, Strand was so tired that he had to stop and was taken to Hammerfest Hospital for intravenous hydration. 

Eight liters of fluid were removed from his muscles and lungs, according to Norwegian broadcaster NRK. He has little recollection of the last moments of the record attempt.

“I had to seek medical help. It may not have been completely unexpected, but at the same time, I hadn’t imagined being able to push myself so hard that I would end up in the hospital,” Strand says, according to NRK.

Daniel Strand recovered quickly in the hospital, but his lung capacity is currently limited.
