RUNmarö semi-marathon 2026

The RUNmarö half-marathon is a road race held in Norrsunda, Värmdö Kommun, Stockholm County, Sweden, set against the backdrop of the Stockholm archipelago. Taking place in mid-July, it features a half marathon of 21.0975 km, a 6 km race named Lunken, and courses for children and juniors, ensuring the day accommodates more than just the main distance. Both adult races consist of single-loop courses: one for the half marathon and one for the 6 km. The route is situated on an island and follows the coastline, with the event's details also highlighting significant monuments along the path. The half marathon is identified as the primary and most attended race, while Lunken provides a shorter alternative on the same island and coast during the race day.
