Hydro Rundt is a local race in Øvre Årdal, Norway, held on a Saturday in September. IL Jotun friidrett organizes it, starting at Torget, the main square in Øvre Årdal.
The race recently returned after a pause of several years. The athletics group at IL Jotun revived it and aims to sustain it, making the event feel like a community restart as much as a race on the calendar.
