Urban Trail Haarlem is a run through the center of Haarlem, with a route designed to showcase the city from both its interior spaces and its streets.

The Haarlem event is limited to 3,000 participants and is now in its sixth edition. The course connects running with culture and architecture, focusing less on achieving a fast time and more on moving through Haarlem’s inner city via locations a normal race would not typically access.

The course visits all eight villages in De Ronde Venen and mixes village roads with open countryside. Runners pass rivers, meadows, a former railway line, a cattle farm, and the Botshol nature reserve. The official description calls the route fast and varied, which fits a course that keeps changing without leaving the flat Dutch landscape. The De Ronde Venen Marathon Foundation organizes the event, and the race is aimed at both recreational runners and more competitive runners who want a full-distance road marathon close to Amsterdam.
