The running conditions in the Reykjavik Marathon are usually extremely comfortable - the route is smoothly paved and very flat, while the weather tends to be breezy and in the mid-teens centigrade. Much of the Reykjavik Marathon route is along the coastline of Reykjavik and Seltjarnarnes, offering participants the benefits of the fresh breeze from the ocean with some blue mountains in the backdrop.
