Magni Maraton is a low-key Cannonball-style race based at Stavset, starting and finishing at the Stavsetsvingen bus stop. It has been held approximately monthly since 2015. The format is intentionally self-managed: runners are responsible for themselves, keep their own time, and record it in the runner’s book upon completion. The race provides marathon, half-marathon, and 10.549 km distances on road.
The marathon consists of eight laps of the Stavset course, with each lap run “towards the sun.” The clock runs continuously, so auto-pause must be deactivated. Finishers receive a medal and an electronic diploma. The series maintains a photo gallery, statistics page, and Hall of Fame for individuals with the most and fastest runs.
