Oslo Half Marathon

Course & Elevation

The Oslo Half Marathon is the 21.1 km race of the DNB Oslo Maraton, held on a Saturday in mid-September in the centre of Oslo. The event is organised by Sportsklubben Vidar and began in 1981 as the Oslo Maraton, with the marathon, a 10 km race and children's runs on the same day. Both start and finish are on Rådhusplassen, in front of City Hall. The half marathon starts at 13:00, in nine waves running up to 13:40. The organisers say the route takes runners past Skøyen, Frogner and Akershusstranda, Aker Brygge, Akershus Fortress, Bislett and Karl Johan. The marathon is run as two laps of the same circuit. The half marathon time limit is 3 hours 30 minutes, and entrants must be at least 15 years old. The event has had low points as well as peaks: Bislett Alliansen cancelled the marathon in 2003 because of low entries, and Sportsklubben Vidar took over the organisation the following year. In 2013 more than 23,000 runners signed up across the event's distances, and the half marathon sold out in 2026.
