Grue Halvmaraton is a half marathon held in Grue, Norway, each May and organized by Grue IL. The series also features Gruemila and Grue Backyard, connecting a small Norwegian running community across road speed, shorter races, and backyard endurance. While the half marathon is the main event, race day includes 400 m and 1.1 km options for younger or less experienced participants.
The course emphasizes speed, promoted as Norway's fastest natural half-marathon route and WA certified for fast times. This identity is reinforced by the phrase "Norway's fastest running village," suiting a race focused on a flat, approved course over scenic mountains or technical terrain. The half marathon is open to ages 15 and up, attracting enough participants for a competitive field while retaining a local-club atmosphere.
