Grimstadvatnet Rundt is a 7.8 km road race starting and finishing at Hareid klubbhus in Hareid, Møre og Romsdal, Norway. It is part of the Hareid winter series, held on the first Saturday of November, December, and January.
The route circles Grimstadvatnet, featuring approximately 70 metres of elevation gain, making it a short course with some undulation. The format is straightforward: a local clubhouse serves as the base, with a road course offering runners multiple opportunities to compete during the darker months of the Norwegian running season.
