Grimstadvatnet Rundt is a 7.8 km road race in Hareid, Norway, starting from Hareid klubbhus in Møre og Romsdal. It is part of the Hareid winter carousel, which includes races on the first Saturday of November, December, and January, offering runners a short, local race series during the colder months.
The route includes approximately 70 metres of elevation gain, making it more than a flat course but still accessible for many club and recreational runners. Hareid IL organizes the event. The name translates to a run around Grimstadvatnet, establishing the race's local identity as a single loop winter event connected to the lake and the Hareid clubhouse.
