The III Bieg po Truskawkę is a 10 km race held in Księży Las, a village within the Zbrosławice municipality in Poland’s Silesian Voivodeship. Taking place in June, the race headquarters and competition office are located at the OSP Księży Las station on Wiejska Street. The primary 10 km run begins first, with a 10 km Nordic walking march commencing a few minutes later.
The course incorporates asphalt roads, dirt tracks, and forest paths surrounding the village. Both runners and Nordic walkers participate, meaning the event welcomes more than just standard road racers. Fundacja Bieg Rolnika, in conjunction with OSP Księży Las and local planter Manfred Skrzypczyk, organizes the race. Support from berry growers is a key aspect, contributing to the event's strawberry theme.
