Bieg Mikołajkowy Wzdłuż Leńcy takes place in Boronów, a village in Poland's Śląskie region, on Saturday 5 December 2026. The day offers a 10 km main run plus a 5 km run and a 5 km Nordic walking category, with the courses following the Leńca watercourse through the surrounding countryside. The name ties the event to St Nicholas, so a December race morning here has a distinctly festive feel. Entries and the latest race-day details come from the organiser's own page.

Other questions
Yes. One of the three events is set aside for Nordic walking over 5 km, so participants using poles have their own start and their own field rather than mixing in with the runners.
The event is scheduled for Saturday 5 December 2026. With a December date in southern Poland, expect a cold morning and plan your clothing and travel accordingly.
The race name says the route runs along the Leńca, the watercourse that gives the event its title. The organiser's page is the place to look for a course map, a profile and any note about how much of the route is on sealed paths versus unsurfaced ground.
