Race Info

The Walls Great Half Antwerpen is a half marathon on Antwerp's Linkeroever, the left bank of the Scheldt River across from the city center. The flat, fully paved course starts and finishes on Kastanjedreef and passes the Galgenweel lake and the marina, keeping the Antwerp skyline in view along most of the route. The race has run under various names since at least 2018; AIMS lists a cancelled 2022 edition, and title sponsor WALLS Vastgoedmakelaars has backed the race since at least 2023. It is now one of three races in organizer Keep on Running's Great Half Series, alongside half marathons in Mechelen and Sint-Truiden.
