Race overview

Amsterdam is the flattest marathon on the European circuit — almost no elevation gain, just a handful of low bridge overpasses. Start and finish inside the 1928 Olympic Stadium. Mid-October weather averages 8–15 °C with high humidity (75 %); the main pacing variable is wind exposure on the Amstel River out-and-back (km 16–28). The course is suited to runners who pace evenly and fuel reliably; there is no terrain to manage.

FAQ

• Is Amsterdam the flattest big marathon?

  Among major European marathons, yes — 38 m of total elevation gain, less than half of Berlin.

• What about wind?

  The Amstel River out-and-back (km 16–28) is exposed. A headwind on the way out becomes a tailwind on the way back, but holding pace through the slow section is the discipline.
