Dziki Bieg w Lesie w Skałowie is a roughly 5 km obstacle race in Skałowo, near the coordinates 52.405568, 17.177000. Runners start at 11:00 in small waves of six people, with a total limit of 222 participants. Some waves are set aside for people racing hard for a result, while the others are for recreational runners who want the mud and obstacles without time pressure.
The route can include swamps, ponds, streams, trees, hills, walls, rope webs, vehicles, muddy pipe-style obstacles, and tasks that require dragging or carrying weight. Anyone who skips an obstacle does 50 squats, while an unsuccessful attempt costs 20 squats, so the race has a clear penalty system rather than just letting people pass difficult sections. Results count under the Grand Prix of Races in the Kostrzyn Municipality, and starting in the wrong wave carries a 70-point penalty.
