Bieg po Kwiat Paproci is a 10-kilometer night run in the Opole region, part of the Grand Prix Opolszczyzny. It takes place around Noc Kupaly, the Slavic midsummer night festival, with the race adopting the old “fern flower” theme rather than resembling a standard road 10K.
The route has previously used the Rzedziwojowice area near Niemodlin, particularly around Staw Mlynski, guiding runners through green spaces, forests, and past fish ponds. Runner accounts characterize it as a relaxed, pleasant course, distinct from a demanding city race. The participants include local club runners who encourage one another, treating the event as a communal gathering.
