Hamarkarusellen Vinter Løp 3 is the third race in the winter series of Hamarkarusellen, held in Hamar, Norway. Each race in this winter series utilizes the same controlled 5 km loop, with all participants starting at 18:00. This format establishes it as a direct evening test race, distinct from complex multi-distance events.
The course follows illuminated walking and cycling paths in the Prestrud area, a practical choice for running in winter after sunset. Participants can choose to walk or run, with or without timing. More competitive athletes can use this loop to race against the clock, compare their performance, or compete with other runners. While official rankings are based on gun time, chip time is also provided in the results. Innlandet Bedriftsidrettskrets is the organizer of this series, which comprises six races throughout the winter season.
