2026 NN Marathon

The NN Marathon The Hague is a new addition to the running calendar and will take place on Sunday 1 November 2026. With an attractive route taking in both The Hague and the Westland region, this event brings runners and supporters together for a unique experience, where the focus is not only on performance but, above all, on connection and exercising together. At the same time, the fast course also offers plenty of opportunities to clock a strong time in an international marathon this autumn.
