The Bieg mikołajkowy in Nasielsk is a December road running event held in this small Mazovian town north of Warsaw. The main race covers 5 kilometres, and separate children's races run alongside it, giving the morning an open, family-oriented feel. It takes place on a Sunday in early winter, so runners can expect cold conditions and a festive, St Nicholas themed atmosphere. Entries and the latest details are handled through the organiser's online entry page.
