Hamburg Marathon

Germany's big spring marathon, held in late April on a largely flat course with few bends. It gives the same April window as Rotterdam with a different kind of day: a loop through a harbor city lined by tens of thousands of spectators, which helps in the miles where pace usually drifts. Records keep falling here, which says more about the course than any brochure: the women's course record went down again in 2026. The race is popular enough to fill up, with all 20,000 entries for the April 25, 2027, edition already taken, so it is one to plan well ahead.
