20 km of Brussels – 20 km through Brussels

The 20 km de Bruxelles – 20 km door Brussel is the long‑standing city road race in Brussels, presented in both French and Dutch and organised for its 46th edition on Sunday 31 May 2026. The course (20.1 km) threads through the capital’s landmark monuments and parks, offering a signature urban route that highlights Brussels’ architectural and cultural sights. The official website states the 2026 edition is sold out and directs late entrants to a waiting list, underlining the event’s popularity and scale.

The event brings together multiple participation categories including runners, walkers and handisport athletes, with designated start windows (handisport, runners and walkers). On‑course support includes six aid stations, Powerade provision and 14 Red Cross medical tents, while finishers receive a medal and can download a diploma. The race is organised by S.I. Brussels Promotion from Rue de la Chapelle, 17 in Brussels and the official event pages provide practical information, route PDF, results and a waiting‑list for registrations.
