Islandsbanki Reykjavik Marathon

Iceland's main marathon gives international runners a compact Reykjavik race weekend, with marathon, half marathon, 10K, and fun run options tied to a citywide celebration.

The marathon uses a Reykjavik city course with competition and general-entry starts for the full marathon and half marathon. The race is organized from central city race-day logistics rather than a remote point-to-point setup.

Late August in Reykjavik can be cool, breezy, and changeable. Runners should plan for wind and damp air while still being ready for bright northern summer light.
