Bieg św. Jakuba is a 10 km street race in Lębork, held annually during Lęborskie Dni Jakubowe, the city’s St. James celebration. It is considered Lębork’s main sporting event, with runners using a certified course through the city streets rather than a trail or park loop.
The route includes historic Staromiejska Street, linking the race to the old part of Lębork. Hundreds of runners and spectators come from Poland and abroad, placing the event within a larger city festival atmosphere that includes a fair and local celebrations. Registration is handled online through Domtel, while local race information is provided by the Lębork sports and recreation center.
