20km Door Brussels

20 km Door Brussel is a flagship road race held in Brussels, Belgium, offering runners the chance to experience the Belgian capital through one of Europe’s most recognizable urban running events. Best known for its 20-kilometre distance and huge citywide atmosphere, the race takes participants past many of Brussels’ most famous landmarks and green spaces, creating a course that feels both scenic and distinctly metropolitan. What makes the event stand out is its broad accessibility as well as its scale: it welcomes runners, walkers, and handisport participants, turning race day into a city celebration rather than a niche competitive event. With decades of history, an enormous field, and a start at the iconic Parc du Cinquantenaire, 20 km Door Brussel has become one of Belgium’s signature mass-participation races and a major annual fixture on the Brussels sporting calendar.
