ForestRun begins and ends at Dzieje park in Murowana Goślina, near Poznań, directing runners into Puszcza Zielonka. The primary events are 10 km and 21 km trail runs, featuring narrow forest paths, soft terrain, and no significant asphalt stretches.
The courses offer a genuine trail running experience without severe elevation changes, making the event suitable for those preferring woodland running over a mountain challenge. It maintains a community atmosphere, including events for younger runners and a race village in a park setting that contributes a relaxed, picnic-like ambiance and a nod to local heritage.
