Islandsbanki Reykjavik Marathon Training Plan

22 August 2026

Reykjavik runs along the North Atlantic coastline in August: part flat, part rolling, always exposed. The temperature is ideal, the air is absurdly clean, and the wind is the entire question.

What the course is actually like

The route combines a loop around Reykjavik and the Seltjarnarnes peninsula with an out-and-back second half, much of it along the coast with ocean on one side and mountains across the bay. The profile is more rolling than flat-course runners expect - a couple of hundred metres of accumulated gain, in gentle instalments rather than real climbs, including green sections through the Ellidaardalur valley.

Exposure is the course's character. Long coastal stretches have no buildings and no trees, and when the wind runs - which on an Atlantic island it often does - there is nowhere to hide from it. The out-and-back at least converts a headwind into a later tailwind, a trade you can plan around.

How to train for it

Prepare for wind as a terrain feature. Long runs on exposed roads or seafronts, held at even effort rather than even pace, are the specific work; a headwind managed calmly costs a minute, a headwind fought costs the race. Modest rolling-terrain work covers the profile.

August means training through your summer for a race in Icelandic conditions - likely cooler than anything you have run in for months. That direction of mismatch is the kind runners enjoy: the race day will feel easy on the lungs. Pack for the other direction anyway; kit for wind and single-digit wind-chill belongs in the bag even if the forecast smiles.

Weather and what to expect on the day

August in Reykjavik typically offers low-teens temperatures - close to physiologically ideal for a marathon - under skies that can produce sun, rain and wind within the same hour. The averages flatter; the variance is the story, and coastal gusts can be strong enough to matter tactically.

The race is woven into Reykjavik's Culture Night, so a small capital turns out in force and the finish feeds into a citywide celebration. Between the clean air, the cool temperatures and the scenery, the day tends to feel better than the wind readings suggest it should.
