Biesak Trail is a mountain race in Kielce, held within the Posłowicki Massif of the Holy Cross Mountains. The primary route covers approximately 13 kilometers, with a 26-kilometer option available for those seeking extended time on the ascents. This event is part of the Kielecki Mountain Race series, now in its 12th edition.
The course directs participants up Pierścienica multiple times, followed by descents on technical, root-covered sections. The terrain also features Kielce stone, requiring strong legs, quick footwork, and good coordination, distinguishing it from steady road running. The finish line is at the Forest Stadium complex, offering open meadows for cooling down or resting. Nearby, the Binkowski Resort provides saunas and saltwater pools for post-race recovery.
