Bialystok Biega 15 Nocna Piatka 2026

The Night 5k is the Saturday-evening race within Białystok Biega, a street-running weekend held in Białystok, located in eastern Poland’s Podlaskie Voivodeship. The event takes place around mid-September, pairing the 5 km night run with a Sunday Fast 10k. This allows runners to select a short evening race or a longer road effort the following day. Białystok Biega began in 2011 as the first event established by the Białystok Biega Foundation, and it remains the foundation’s oldest race project. The Night 5k has a participant limit, and the edition mentioned in the source filled all available spots. The races utilize city streets, broad avenues, and green central areas of Białystok, concluding near the Ton cinema. The weekend is not exclusively for adult road runners; it commences with Moltani Kids Run events, featuring routes for children and juniors. These children's races attract over 2,000 young participants. The field size is substantial by regional measures, with Białystok Biega recognized as one of the largest running events in this region of Poland. Its identity is clear: a city race weekend comprising a night 5k, a Sunday 10k, and an extensive children's program.
