Course & Elevation
The Midnight Sun Marathon is a road marathon in Tromsø, northern Norway, held on a Saturday in June around the summer solstice, when the sun does not set. It is organised by the Midnight Sun Marathon Foundation and is a member of AIMS, with all courses measured and certified. The marathon starts and finishes in the city centre and crosses the Tromsø Bridge twice; the bridge rises from 6 to 43 metres above sea level. Shorter races are offered alongside it, including a half marathon, a 10 km and a children's race, for five distances in all. The finish closes at 2:00am, the marathon has a time limit of 5 hours 30 minutes and the half marathon 3 hours 30 minutes, and runners must be at least 18 for the marathon. The first Midnight Sun Marathon took place in July 1990. In 2025 the race set a participation record with almost 9,000 runners from 88 nations across all distances.
