Atom'Run

Atom'Run is a road relay held in late November in Brussels, Belgium, starting at the King Baudouin Stadium in Laeken. The event is designed for teams of four, using a 4 km loop as its core component. This format is suitable for friends, colleagues, families, and regular runners seeking a brief, shared activity over a lengthy individual competition. The relay structure defines the race: the initial runner runs a 4 km loop, then a teammate takes over in the relay zone. This continues until all four team members have participated. Consequently, the first runner completes the longest distance, and the last runner covers a single loop. A children's race with 1 km loops is also available. The event is organized by Run-for-Resc of Excelsior, is included in the Run in Brussels challenge, and contributes a portion of its profits to the Centre d'Entraide de Laeken association.
