Race Info
The TREK Antwerp Marathon runs through central Antwerp, Belgium, each October, with a marathon, half marathon, and 10K held on the same day. The marathon starts near the Kattendijkbrug in the Eilandje docklands and finishes at the MAS museum, passing the Cathedral of Our Lady, the Grote Markt, and the Scheldt river quays along the way. Golazo Sports organizes the race, which began in September 2021 as the Port of Antwerp Night Marathon before moving to an October date and taking on its current TREK sponsorship. The 2025 edition drew about 20,000 runners across all three distances.
