Półmaraton Bydgoski - Festiwal Biegów is a two-day street running event in Bydgoszcz, held at LPKiW Myślęcinek in late September. The program includes the Night 10, a 10 km race that starts at 9:00 PM, plus a 5 km race the next afternoon. Despite the half-marathon name, the listed races for this edition focus on shorter distances and family participation.
The Night 10 uses a simple 5 km loop that runners complete twice, which makes the evening race easy to follow for spectators and straightforward for pacing. Children race before the 5 km event, with distances matched to school age: about 300 m for preschoolers through fourth grade, 600 m for fifth and sixth graders, and 900 m for seventh and eighth graders. This is the third edition of the festival, and the official site is polmaratonbydgoski.pl.
