Course & Elevation
The Oslo Maraton, currently the DNB Oslo Maraton, is a city marathon in the centre of Oslo, held on a Saturday in September with start and finish on Rådhusplassen, the City Hall Square. It was first held in 1981, went through a decline around the turn of the millennium, and has been organised by Sportsklubben Vidar since its revival in 2004. The marathon is two laps of the half marathon route, and the half marathon, a 10 km race called 10 for Grete and children's races run on the same day. The route changes in detail from year to year, and the organisers present each year's map ahead of the event. In recent years the half marathon lap has run from the City Hall along Drammensveien, around Frognerparken and down to Skøyen, then back towards the City Hall and along Akershusstranda, with a loop around St. Hanshaugen before the half marathon finishes. The organisers give the marathon about 350 m of climbing in total and a time limit of 6 hours, with the halfway point to be passed in under 3 hours. Entry for the 2027 marathon is NOK 1,350, and the race has sold out well before race day in recent years. Race numbers are collected at the expo in the days before.
