Svalandsgubben Skauløp challenges runners across bogs, mud, and uneven terrain on Svalandsheia in Birkenes, Norway. The primary event, Gubben, is a challenging 27 km trail loop beginning and ending in Birkenesparken in Birkeland. It takes place annually on the last Sunday in October, continuing a tradition since 1974, where elite and amateur runners navigate the same rugged autumn course. The series also features Kortgubben, a 13 km race for junior women and men, and Minigubben, a 5 km race for children and youth.
The course crosses Svalandsheia instead of utilizing simpler roads, meaning mud, wet ground, and varied terrain are integral to the event. Supporters line the more difficult parts with flags and encouragement, contributing to the race's local, hillside atmosphere. The concept originated during cherry picking at Kristian Svaland’s farm, when he spoke about the course with brothers Trygve and Torfinn Løland. Minigubben begins near Mollestadeika, an oak approaching 1,100 years old and Norway’s second-largest tree, and the marked main course is also accessible as a hiking path throughout the year.
