Organizers: Náttúruhlaup and Arctic Running

Náttúruhlaup (Nature Running) is the local branch of Arctic Running. While Arctic Running offers Running Tours in Iceland for visitors, Náttúruhlaup is a running community for local runners. Arctic Running/Náttúruhlaup held the Iceland Backyard Ultra for the first time in September 2020. It sold out quickly and was a huge success. We look forward to see you in the Backyard races in 2025!
