Bieg po aronię is a 10 km race held in late summer in Kolonia Bądków, within the Goszczyn commune of Mazowieckie. A 10 km Nordic Walking event covers the same distance, with runners and walkers sharing the program. Fundacja Bieg Rolnika organizes the event with ARONIA EGGERT Sp. z o.o., and the race headquarters are located at the co-organizer's site.
The route crosses plantation areas before utilizing municipal and district roads surrounding the village. The terrain varies between asphalt, paved surfaces, and dirt roads, providing the 10 km with a rural, mixed-surface character instead of a standard road race. Water and aid stations are available along the course, with judges assigned to the Nordic Walking section. Chip timing is provided via bib numbers, and participants receive starter packs and commemorative medals.
