The Tyski Bieg Morsów: Mokre Majtki vs. Suche Majtki is a cold-weather race at Lake Paprocańskie in Tychy. Participants choose between running dry or running and entering the lake. The main route covers about 6.2 km, a single loop around the water. The event combines running, winter swimming, nordic walking, and outdoor activity in a playful format. It welcomes beginners and experienced runners, including those curious about cold water but not yet ready to race through it.
There are three categories, with names that reveal the event's humor. Mokre Majtki is for runners who enter Lake Paprocańskie three times during the course, with each water segment approximately 100 meters. Suche Majtki is the dry option for runners completing the loop without ice swimming. Suche Kije is for nordic walkers who remain on land. The race focuses less on a standard road-running format and more on selecting one's preferred level of discomfort. The wet category adds a real test of cold tolerance to a short lakeside loop.
