Semi-Marathon de Nivelles

The Semi-Marathon de Nivelles is a half marathon in Nivelles, in Walloon Brabant, Belgium, and the largest running event in the province. It has run as the EnergyVision Semi-Marathon de Nivelles and is the seventh stop of the nine-race EnergyVision Running Tour. The 13th edition took place on Sunday 20 September 2026 with more than 5,000 runners, and the next edition is expected on the third Sunday of September 2027. The half marathon starts at 10:30 on the Grand Place, beside the Collégiale Sainte-Gertrude, and finishes there. The course leaves the Grand Place for Les Monstreux, reaches the athletics track in the Parc de la Dodaine, then loops through Thines and Baulers before the finish. The 21.097 km route is certified, so personal records count. Runners must be 16 or older on race day. A 12K, a 5K and a 1 km kids run start from the same square.
