Benefiet tegen Kanker is a late-May neighborhood running event in Affligem, Flemish Brabant, centered on a cancer-benefit fundraiser. The program is straightforward and local: kids' races for three age groups, a 4.2 km family run for adults, and a 10.5 km adult race. The start and prize ceremony take place at Café Onder Den Toren on Kerkstraat, with parking at Bellekouter.
The children’s races are divided into groups for ages up to 5, 6 to 8, and 9 to 11, ensuring the youngest runners are not grouped with older children. Adults can opt for the shorter family distance or the 10.5 km race, where the top three women and top three men receive prize money. All participants receive a natural prize, contributing to the event's small-community atmosphere over a purely competitive one.
