During the Polar Night Marathon you run in the middle of the day in the blue, Arctic light that characterizes the period before the sun returns.
What this race demands
The Polar Night Marathon requires athletes to sustain a standard full-marathon distance in deep winter Arctic conditions with limited daylight.
Distance endurance
Covering the full 42.2 km marathon distance places continuous load on the musculoskeletal system, demanding significant aerobic capacity and pacing discipline.
Cold-weather management
Taking place in Tromsø in January during the polar night means athletes must manage core temperature and performance under cold, dark seasonal conditions.
A marathon duration typically exceeds 2.5 hours, so athletes should aim for a consistent intake of 60 to 90 grams of carbohydrates per hour to maintain output.
