Two of the fastest marathon courses on earth, two very different races. Here's every stat, side by side, to help you pick.
Indicative — based on GPX data. Both courses normalised to start at 0m.
✓ marks the better number on that stat.
Two of Northern Europe's flattest marathons. Amsterdam is marginally flatter (55m of gain) than Copenhagen (75m of gain), and its course record (2:03:30) is meaningfully faster than Copenhagen's 2:08:23 — a gap likely down to field depth as much as terrain, since neither course is genuinely hilly.
Copenhagen runs in May through the city's canals and Nyhavn waterfront; Amsterdam runs in October along the city's own canal network. Both are open registration with straightforward entry. If pure speed is the goal, Amsterdam's course record suggests it's the faster option; if timing or a spring date works better, Copenhagen is an equally flat, scenic alternative.
