Across the weekend of 6–8 February 2026, Bislett Stadium hosts the Bislett Indoor Marathon, a multi-day meet where runners choose anything from a short 3 km blast up to a full 50 km ultra, all run on the same indoor track. The surface is a certified, 114-metre oval with zero elevation change, so every distance is completed in tightly counted laps—perfect for pacing, but a real mental challenge as the numbers tick up. Several start times are spread over the three days and athletes can set up their own food and drink on tables by the track, turning the stadium into a contained endurance arena with constant climate and no weather worries. Whether someone is chasing a marathon PB, stepping up to an indoor ultra or just curious about racing on a famous athletics track, the event offers a very specific kind of “laps-only” experience.
