Ultras Oliwski Bieg Wokół Radości is a trail race in Gdańsk, Poland, offering 10 km and 22 km distances. It takes place in the moraine hills of the Tricity Landscape Park, meaning the course involves technical forest trails, mud, and significant elevation changes, not a flat seaside run.
The start and finish are located in one of Gdańsk’s most appealing districts, with runners concluding near the walls of a historic cathedral. The 22 km Bieg Główny is the longer race, and the 10 km Olivia Centre Run is the shorter option. The event attracts trail runners who appreciate challenging terrain and climbing, and it has cultivated a dedicated following across its editions. Organizers highlight the post-race recovery, which seems to be a draw after the final descent toward Oliwa.
