The Urodzinowy Festiwal Biegowy Dzialdowo is a running event in Dzialdowo, part of the city's August birthday festivities. Its primary race, the Dzialdowska Dycha, is a 10 km run now integrated into a larger festival. This format also includes a 5 km run and a 5 km Nordic Walking option. Both the start and finish lines are located at the MOSiR Stadium on Robotnicza Street. The Municipal Sports and Recreation Center and the City Hall jointly organize the event.
The festival attracts over 400 participants across all its races, with approximately 120 being children. Runners and walkers travel from across Poland, with notable contingents from Warsaw and Olsztyn, and even participants from Lithuania. Shorter children's races, ranging from 50 m to 800 m, take place within the stadium. The adult courses feature water stations, and the finish area provides medals, prizes, and refreshments. The recently introduced 5 km race has gained significant popularity, expanding the event's scope beyond a single 10 km road race.
