3-Sjøersløpet is a November half marathon in Stavanger, Norway, centered on three lakes near the city. The race begins and ends at Tjensvoll, approximately 3 km from central Stavanger. Messehallen Forum Expo serves as the primary indoor space before and after the run. Approximately 5,200 runners are anticipated, with pacemakers provided for those aiming for a specific time.
The route utilizes the lakeside paths commonly used by locals for walking and jogging, giving much of the race a park-like feel rather than a typical road-only half marathon. Roughly four-fifths of the distance is on gravel, with the rest on asphalt. Participants receive a concise tour of Stavanger’s lake districts, encountering spectators, flags, and music along the way.
