Festiwal Słońca is a race weekend in Gołąbki, Wielkopolskie, starting and finishing at the Jutrzenka Recreation Center. The main events include trail runs of 10 km, 25 km, and 50 km. Additionally, there is a 10 km Nordic walking race, relay races, a Royal Marathon competition, children's races, and a Beer Mile. The festival takes place in mid-August, with the Beer Mile scheduled independently from the primary races.
The 10 km run, 25 km run, and 10 km Nordic walking race follow single-loop courses. A new 25 km loop has been introduced for this edition. The event accommodates a wide range of participants: trail runners, Nordic walkers, relay teams, Beer Mile competitors, and families with children. Younger children can participate in non-competitive Fun Runs, which offer 150 free entries and a cast metal finisher medal. The festival is organized by Gmina Trzemeszno and the Aktywne Trzemeszno Foundation. Registration is done online, followed by in-person verification at the race office with identification.
