Oslo Marathon
The Oslo Marathon runs through the Norwegian capital on a multi-loop course that rewards steady, patient racing. It is a genuine test with real elevation, set against a city that knows how to throw a race-day party.
Race Overview
The Course
Race-Day Weather
September in Oslo tends to be cool and manageable. You will likely start in the low-to-mid 40s and finish somewhere in the low 60s, which is solid marathon weather if you dress right. Bring a throwaway layer for the corral. The bigger variable is cloud cover and wind off the waterfront, which can make the start feel sharper than the numbers suggest. It is generally a good window for running hard, but Oslo weather can shift, so check the forecast in the days before and don't assume it stays mild all morning.
Entry
Registration is open on a first-come, first-served basis with tiered pricing. Marathon, half marathon, and Oslo Triple are typically sold out; runners can join waiting lists for resale access.
