This summer, he finished with Martin Johnsrud's Sundby's long-distance running team Team Koteng Eidissen, something he is now dropping out of.

“I took part in a show race in Mosjön and broke my shoulder.
I tried with both rehab and surgery to get back to my previous levels but have not managed to create enough power in my staking.

Dyrhaug has not had any major successes since the winter of 2018.
