Sörmland Ultra Marathon
The Sörmland Ultra Marathon, commonly referred to as SUM, is an endurance event covering a distance of approximately 50 km. The course is situated in the southern Stockholm area and primarily follows the first four stages of the Sörmlandsleden trail.

Participants pass a variety of landscapes including golf courses, horse paddocks, cottages, and small lakes. A specific feature of the current course includes a crossing over a bridge toward Tyresta after passing Alby Friluftsgård, while maintaining the passage through Nyfors with views over Tyresö-Flaten.
