Why Choose the Half Marathon?
The half marathon is the ideal distance for runners who want a real challenge without the extreme training load a full marathon demands. 21.1km is ambitious enough to deliver a genuine sense of achievement, but the shorter training time makes it achievable for most busy people with 8–12 weeks of preparation.
The Oslo Half Marathon shares the course with the full marathon and passes through Oslo's finest areas: along the Oslofjord, through Aker Brygge and Frogner. It is one of Norway's most popular half marathon events, attracting thousands of runners each year.
