Tromsø Midnight Sun Marathon

The Midnight Sun Marathon is the world’s northernmost marathon certified by the Association of International Marathons and Distance Races (AIMS). Held annually in June in the Norwegian city of Tromsø, the race starts and finishes in Tromsø’s city center with a scenic course that includes two crossings of the iconic Tromsø Bridge. Due to the city's location about 350 kilometers north of the Arctic Circle, the event is known for offering runners the rare experience of racing under the natural phenomenon of the midnight sun.
